What is the simplest form of following expression?
7x2y – 7xy + 5xy2 – 5xy + x2y – xy2

The expression equivalent to 30÷(3+x) is 30 divided by (x+3).

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the expression x/2 + 6. Complex riddles are solved using mathematical expressions.

Given:

30÷(3+x)

Now, we know the fraction form of is written as x/y, where x is numerator and y is denominator.

So,  Numerator = 30

Denominator = (3+x)

Hence, the expression 30/ (3+ x)

im not really sure what your asking here. could you explain the question a little bit more? good luck :)

Answer:

v = 13.5m/sec

Step-by-step explanation:

v = u + at

u = 3m/s

a = 1.5m/s^2

t = 7 sec

v = 3 + 1.5×7

v = 3 + 10.5

v = 13.5m/s

Answer:

diameter: 240 ft

radius: 120 ft

circumference: 240π ft or 753.98ft

Step-by-step explanation:

14,400π ft^2 is the area and you find the area of a circle using the equation

πr^2

if you write that πr^2  = 14,400π ft^2, then you can solve for the radius

divide each side by π and then put the 14,400 into a radical

you will get the answer 120 meaning that your radius is 120 ft.

Radius is one half of the diameter so just multiply 120 by 2 to get a diameter of 240 ft

finally, the formula for the circumference of a circle is 2πr

we know that the radius is 120 so we plug it in: 2(π)(120)

the answer you get is 240π or about 753.98 ft

Answer:

t<10

Step-by-step explanation:

S = {v₁, v₂, v₃} is linearly independent, which means

c₁v₁ + c₂v₂ + c₃v₃ = 0

if and only if c₁ = c₂ = c₃ = 0.

T = {w₁, w₂, w₃} = {2v₁ + v₂ - 2v₃, 4v₁ + 3v₂, 3v₁ + 2v₂ - v₃}

is linearly independent if the same is true for the vectors w₁, w₂, w₃, i.e.

c₁w₁ + c₂w₂ + c₃w₃ = 0

iff c₁ = c₂ = c₃ = 0.

Expanding this equation, we get

c₁ (2v₁ + v₂ - 2v₃) + c₂ (4v₁ + 3v₂) + c₃ (3v₁ + 2v₂ - v₃) = 0

(2c₁ + 4c₂ + 3c₃) v₁ + (c₁ + 3c₂ + 2c₃) v₂ + (-2c₁ - c₃) v₃ = 0

Put the coefficients of v₁, v₂, v₃ in this expansion into an augmented matrix and solve the linear system:

[tex]\left[\begin{array}{ccc|c}2&4&3&0\\1&3&2&0\\-2&0&-1&0\end{array}\right][/tex]

Row-reduce the matrix:

• Replace row 2 with [row 1 + (-2) row 2]:

[tex]\left[\begin{array}{ccc|c}2&4&3&0\\0&-2&-1&0\\-2&0&-1&0\end{array}\right][/tex]

• Replace row 3 with [row 1 + row 3]:

[tex]\left[\begin{array}{ccc|c}2&4&3&0\\0&-2&-1&0\\0&4&2&0\end{array}\right][/tex]

Right away, we see that row 3 is a scalar multiple of row 2, since row 3 = -2 (row 2), so T is not linearly independent.

Continuing with the row reduction, we'd end up with

[tex]\left[\begin{array}{ccc|c}2&0&1&0\\0&2&1&0\\0&0&0&0\end{array}\right][/tex]

so if we choose, for instance, c₃ = 1, so that c₁ = c₂ = -1/2, we get

-1/2 (2v₁ + v₂ - 2v₃) - 1/2 (4v₁ + 3v₂) + (3v₁ + 2v₂ - v₃)

= (-v₁ - 1/2 v₂ + v₃) + (-2v₁ - 3/2v₂) + (3v₁ + 2v₂ - v₃)

= (-1 - 2 + 3) v₁ + (-1/2 - 3/2 + 2) v₂ + (1 - 1) v₃) = 0

Answer:

x-intercept=(4,0)

y-intercept=(0,3)

Slope=-3/4

Step-by-step explanation:

the last number is the y-intercept. The y-intercept is 3. Starting at that point, you know that 3/4 is the slope. So count up 3 (rise is 3) and count left 4 (run is 4) to find x. X-intercept would meet at (4,0)

Answer:

Congruent

Step-by-step explanation:

There are two triangular panels ΔABC and ΔDBE used in the gate.

Since, ∠ABC ≅ ∠DBE [Given]

∠ACB ≅ ∠DBE [Given]

AB ≅ DE [Given]

Therefore, by AAS postulate of congruence, both the triangles will be congruent.

ΔABC ≅ ΔDBE

Hence, we can say that the solid panels used in the gate are congruent.

The two solid triangular panels are congruent by the AAS Congruence Theorem.

When two angles and a non-included side of a triangle are congruent to two angles and a non-included side of another, the triangles are congruent by the AAS Congruence Theorem.

Answer:

The value of x = 175.4 mm

Step-by-step explanation:

The given triangle is a right-angled triangle.

Given

Ф = 70

To determine

hypotenuse = x

We know that the trigonometric cosine ratio can be represented as

cos Ф = adjacent / hypotenuse

here

substituting the values

cos Ф = adjacent / hypotenuse

cos 70 = 60 / x

x = 60 / cos 70

x = 175.4 mm

Therefore, the value of x = 175.4 mm
