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.

Answer:

No they will not reach their goal because they made $310 which is less than $400.

Step-by-step explanation:

Part A the inequality:

You want to make at least 400 or more on the fundraiser, so use greater that or equal to. I used h to represent holiday cards and w to represent wrapping paper.

[tex]1.50h + 1.00w \geq 400[/tex]

Part B:

[tex]1.50h + 1.00w \geq 400\\1.50(100)+1(160)\geq 400\\150+160\geq 400\\310\geq 410[/tex]

No they will not reach their goal because they made $310 which is less than $400.

The coordinates of dilated triangle A' B'C' is A'(-12, 9), B'(9, 9) and C'(6, -3).

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Dilation is the increase or decrease in size of a figure by a factor k. If point A(x, y) is dilated by factor k, the new point is at A'(kx, ky).

ABC is located at points A(-4,3),B(3,3)and C(2,-1). If it is dilated by a factor of 3, the new points is at:

A'(-12, 9), B'(9, 9) and C'(6, -3).

2.5×103 times 2.058 number is equal to 5×106.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

We know N = DQ + R, where N = number, D = divisor, Q = quotient, and R = remainder.

Let, 'x' times 2.5×103 is equal to 5×106.

Therefore,

(2.5×103)x = 5×106.

x = (5×106)/(2.5×103).

x = (2×106)/103.

x = 212/103.

x = 2.058

Answer:

The graph takes 299 units width and intervals are of width  10, thus we can do division.

The number of intervals of width 10 needed to draw the given graph is specified by:

Option D: 25 or more.

Number of intervals with width 10 units needed to draw this graph correctly.

Range = Maximum value - minimum value = 299 - 0 = 299

If the width of intervals used is 10, then

[tex]\text{Number of intervals needed } \geq \dfrac{Total width}{width of interval} = \dfrac{299}{10} = 29.9\\\text{Number of intervals needed} = 30[/tex]

We took greater or equal since we don't want to leave some points of the graph out, thus we ensure taking enough amount of intervals so as to cover the whole graph even if some space is remain unused in intervals.

Thus, Option D: 25 or more is correct option as 30 is more than 25.

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]

Step-by-step explanation:

17. A regular hexagon, which means a hexagon with equal sides and equal interior angles, is the shape that has 3 pairs of parallel sides. Since PQ is parallel to BC, QR is parallel to CD, RS is parallel to DE, TS is parallel to FE, the angles of smaller hexagon are the same. Since both hexagons have the same angle at ∠A, all the angles are the same

(a) so CDE = QRS

(b) AT = 3PB

since AT = AP

if length of AB is 1, then length of AP is 3/4

so perimeter of larger hexagon is 6 x 1 = 6

perimeter of smaller hexagon is 6 x 3/4 = 4.5 or 4 1/2

18. If X is midpoint between A and Y and MX is perpendicular to AY just like BY, then M is midpoint between A and B so MX = 1/2BY

(a) BY = 2MX = 2(1.4) = 2.8

(b) In construction to build the A - frame houses as the frame helps to reflect the similarity due to similar triangles when the bar of the frame is placed parallel to the ground.
