Answer:

$-24$

Step-by-step explanation:

We have been given an expression $-24x^7y^3$ . We are asked to find the coefficient of given expression.

We know that a coefficient is a constant quantity, which is multiplied by the variable in an algebraic expression.

Upon looking at our given expression, we can see that $x^7\text{ and }y^3$ are variables. The variables are being multiplied by $-24$ .

Therefore, the coefficient of the given term would be $-24$ .

the area of a window is 192 in squared. The width if the window is four inches more than half the length of the window. What are

Leya [2.2K]

Answer:

Length = 16 inches and width = 12inches

Step-by-step explanation:

A = 192 in² . The width is 4 + 1/2x. therefore let x = length

Area = LW

192 = x(4 + 1/2 x)

192 = 4x + 1/2x²

384 = 8x + x² Multiply each term by 2 to make a

384 + 16 = x² + 8x + 16 Complete the square

400 = (x + 4)²

$\sqrt{400} = \sqrt{(x + 4)^2}$

± 20 = x + 4

20 = x + 4 or -20 = x + 4

20 - 4 = x or -20 - 4 = x

16 = x or -24 = x reject the negative amount

Length = 16

width = 4 + 1/2(16); 4 + 8 = 12

$\dfrac{c^2-4}{6c^4+15c^3}\div\dfrac{c^2+4c+4}{12c^3+30c^2}=\dfrac{c^2-2^2}{3c^3(2c+5)}\div\dfrac{c^2+2(c)(2)+2^2}{6c^2(2c+5)}\\\\_{\text{use}\ a^2-b^2=(a-b)(a+b)\ \text{and}\ (a+b)^2=a^2+2ab+b^2}\\\\=\dfrac{(c-2)(c+2)}{3c^3(2c+5)}\cdot\dfrac{6c^2(2c+5)}{(c+2)^2}=\dfrac{(c-2)}{c}\cdot\dfrac{2}{(c+2)}=\boxed{\dfrac{2(c-2)}{c(c+2)}}$

In parallelogram DEFG, DH = x + 3, HF = 3y, GH = 4x – 5, and HE = 2y + 3. Find the values of x and y.

marissa [1.9K]

Here, DH = HF

x+3 = 3y

x = 3y-3 ----(I)

GH = HE

4x-5 = 2y+3

4x = 2y+8

Substitute value of x,

4(3y-3) = 2y+8

12y-12 = 2y+8

12y-2y = 12+8

10y = 20

y = 2

Now, substitute it in equation 1,

x = 3(2)-3

x = 6-3 = 3

So, your final answer is x=3 & y=2

Rectangle with area of 12 square units is dilated by a scale factor of 3. What is the area?

Olegator [25]

Answer:

36 units²

Step-by-step explanation:

rectangle with area of 12 square units is dilated by a scale factor of 3. What is the area?

Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

we use the inverse formula

12 * 3 =

36 units²

-----------------------

check

36 : 12 = 3

the answer is good
