Answer:

Area = -20x + 100
Perimeter = -4x + 40

Step-by-step explanation:

Given rectangle with

Length l = - 2x + 10
Width w = 10

To find

Area
Perimeter

Solution

A = lw
A = (-2x + 10)*10 = -20x + 100
P = 2(l +w)
P = 2( -2x + 10 + 10) = 2( -2x + 20) = -4x + 40

Determine whether 81 − 49n4 is a difference of two squares. If so, factor it. If not, explain why.

Mumz [18]

We have

$81-49n^4=9^2-(7n^2)^2$

so this is indeed a difference of squares. Factorizing would give

$81-49n^4=(9-7n^2)(9+7n^2)$

making the answer D.

We can further factor the first term here and write

$9-7n^2=3^2-(\sqrt 7\,n)^2=(3-\sqrt7\,n)(3+\sqrt7\,n)$

but that's clearly out of the scope of this question.

Which expression is equivalent to the following: * 20x+9y

anzhelika [568]

Answer:

B. 5(4x+2y)-y

Step-by-step explanation:

Bring the 5 over and multiply

5×4 = 20 + x

=20x (thats the beginning of the expression)

5×2 = 10

10y - y = 9 because the - y is basically telling you to get rid of one of the y values so 10 - 1 = 9y
