Algebraic expression is the combination of variables, coefficients and the constants. The phrase 2,4 and 5 represents the given algebraic equation.

Given information-

The given algebraic expression in the problem is,

[tex]x+14[/tex]

Algebraic expression is the combination of variables, coefficients and the constants.

Above expression has the a unknown number [tex]x[/tex]. The expression refer that the number 14 is added in the unknown number [tex]x[/tex].

Lets check all the phrase one by one,

The option 1 is the quotient of a number and 14. Here the unknown number is [tex]x[/tex]. Thus the expression for this option can be given as,

[tex]=\dfrac{x}{14} [/tex]

This phrase does not represent the given expression. Thus the option 1 is incorrect option.

The option 2 is a number plus 14. Here the unknown number is [tex]x[/tex]. The term plus refers the addition of 14 in the unknown number.Thus the expression for this option can be given as,

[tex]=x+14[/tex]

This phrase represents the given expression. Thus the option 2 is correct option.

The option 3 is fourteen less than a number. Here the unknown number is [tex]x[/tex]. The term less than refers to subtract 14 from the number. Thus the expression for this option can be given as,

[tex]=x-14[/tex]

This phrase does not represent the given expression. Thus the option 3 is incorrect option.

The option 4 is fourteen more than a number. Here the unknown number is [tex]x[/tex]. The term more refers the addition of 14 in the unknown number. Thus the expression for this option can be given as,

[tex]=x+14[/tex]

This phrase represents the given expression. Thus the option 4 is correct option.

The option 5 is a number increased by 14. Here the unknown number is [tex]x[/tex]. The term increased refers the addition of 14 in the unknown number. Thus the expression for this option can be given as,

[tex]=x+14[/tex]

This phrase represents the given expression. Thus the option 5 is correct option.

Hence the phrase 2,4 and 5 represents the given algebraic equation.

Answer:

27 pages.

Step-by-step explanation:

100% = 45 pages

1% = 45 / 100 = 0.45

pages left = 100% - 40% = 60%

so, 0.45 × 60 = 27.

Answer:

identification from the table given below. use y = mx + c to solve

Step-by-step explanation:

y = 3x  to third

y = 1.5x -7 to second  

y =7 to first

y = -1.5x-4 to fifth

y = -3x+4 to fourth

Answer:

Below!

Step-by-step explanation:

Let's use the formula to identify the correct slope and y intercept.

We know that:

Option 1: (y = 3x)

Let's compare y = 3x with the formula.

We can clearly see that the slope(m) is 3 and the y-intercept(b) is 0.

Final answer: m = 3, b = 0

__________________________________________________________

Option 2: (y = 1.5x - 7)

Let's compare y = 1.5x - 7 with the formula.

We can clearly see that the slope(m) is 1.5 and the y-intercept(b) is -7.

Final answer: m = 1.5, b = -7

Option 3: (y = 7)

Let's compare y = 7 with the formula.

We can clearly see that the slope(m) is 0 and the y-intercept(b) is 7.

Final answer: m = 0, b = 7

Option 4: (y = -1.5x - 4)

Let's compare y = -1.5x - 4 with the formula.

We can clearly see that the slope(m) is -1.5 and the y-intercept(b) is -4.

Final answer: m = -1.5, b = -4

Option 5: (y = -3x + 4)

Let's compare y = -3x + 4 with the formula.

We can clearly see that the slope(m) is -3 and the y-intercept(b) is 4.

Final answer: m = -3, b = 4

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length. The y value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Given information-

The coordinates of the point E is (2,-3).

the coordinates of the point F is (-2,-1).

As the 3/4 the distance from the point E is the point F is means the points which divides the line EF in the ratio of 3/1.

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length.

Suppose the ratio [tex]m:l [/tex] are the ratio of the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. Then the coordinate of the point which divide the line at this ratio can be given as,

[tex](x,y)=\left ( \dfrac{mx_2+lx_1\tiems}{m+l} ,\dfrac{my_2+ly_1}{m+l} \right )[/tex]

Put the values,

[tex](x,y)=\left ( \dfrac{3\times (-2)+1\times(2)}{3+1} ,\dfrac{3\times (-1)+1\times(-3)}{3+1} \right )[/tex]

[tex](x,y)=(-1,-1.5)[/tex]

Thus the y value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

7x+5y

Answer:

2x+2y

Step-by-step explanation:

Start by factoring out the equation to two binomials:

[tex]x^2+2xy+y^2=(x+y)^2=(x+y)(x+y)[/tex]

We add up both binomials and we get:

[tex](x+y)+(x+y)=2x+2y[/tex]

The sum of these two binomials will be 2x + 2y. Then the correct option is C.

A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.

The trinomial is given below.

⇒ x² + 2xy + y²

Convert the trinomial into the product of two binomials. Then we have

⇒ x² + xy + xy + y²

⇒ x(x + y) + y(x + y)

⇒ (x + y)(x + y)

The sum of two binomials is given as,

⇒ (x + y) + (x + y)

⇒ 2x + 2y

The sum of these two binomials will be 2x + 2y. Then the correct option is C.

Triangle DEF is shown.

Angle DFE is 90 degrees and angles FDE and DEF are 45 degrees.

The lengths of sides DF and FE are 36 units.

We have to determine

What is the length of the hypotenuse of the triangle?

According to the question

The length of the hypotenuse is determined by using the Pythagoras theorem following all the steps given below.

The length of the hypotenuse is determined by;

[tex]\rm (Hypotenuse)^2= (Base)^2+(Perpendicular)^2\\\\ (Hypotenuse)^2= (36)^2+(36)^2\\\\ (Hypotenuse)^2= 1296+1296\\\\ (Hypotenuse)^2= 2592\\\\ Hypotenuse = \sqrt{2592}\\\\ Hypotenuse = \sqrt{2\times 4 \times 4\times 9\times 9}\\\\ Hypotenuse= 9 \times 4 \times \sqrt{2}\\\\ Hypotenuse= 36 \sqrt{2}\\[/tex]
