Whatever is inside of the ( ), simply plug that digit into the x-values for f(x)
So: f(x) = 7x - x^2, and f(7+h) - f(7)
= [7(7+h) - (7+h)^2] - [7(7) - (7)^2]
= [49+7h - 49+14h+h^2] - [49-49]
= 49-49 + 7h+14h + h^2 = h^2 + 21h =
h (h+21), h (h+21) = 0
h=0... But it stated h cannot = 0
So h+21 = 0, h = -21

Help me with this!!

Answer:

Step-by-step explanation:

so we see the two line of the same length of 14, which tells us that the lengths of 5x  and 7x-8  have to be the same length.  so we know we can set them equal to each other.  Often times that's the key to math problems , finding where you can set things equal.

5x = 7x-8  ( subtract 5x from both sides and then add 8 to both sides )

8 = 2x ( divide both sides by 2 )

4 = x

nice this looks right too  , both sides add to 20  :)

-2

Divide each term (-4x = 8 by -4)

Cancel the common factor of -4

x = 8/-4

THEN DIVIDE

x=-2

miskamm [114]

Answer: A - 30 cubes

B - Volume of prism =  feet³

Step-by-step explanation: We are given that the dimensions of the rectangualr prism is,

Length =  =  feet

Width = 1 foot

Height =  =  feet

Thus, the volume of the prism = Length × Width × Height

i.e. Volume of the prism =  × 1 ×  =  feet³

Now, the side of the cube =  foot each.

Volume of the cube =  =  feet³
