Let L, H, W be the length, height, and width.

Using the 3 clues they gave us, we have:

L x W = 12

L x H = 8

W x H = 6


Our goal is to figure out volume: L x W x H

One way of solving this is to just randomly plug in numbers which should be easy to do for this problem.

Another way is to use substitution.

From first equation: L = 12/W

Plug that into second equation:

12/W x H = 8,

H = (8/12)W = (2/3)W

Plug that into the third equation:

W x (2/3)W = 6,

W x W = 9

W must be equal to 3.

And since we know that L x H = 8

Then L x H x W = (8) x 3 = 24 cm^3

Find the values if a and b such that x squared + 2x -7 = (x+a) squared + b​
stealth61 [152]

Given:

x^2+2x-7=(x+a)^2+b

To find:

The values of a and b.

Solution:

We have,

x^2+2x-7=(x+a)^2+b

It can be written as

(x^2+2x)-7=(x+a)^2+b

Add and subtract square of half of coefficient of x in the parenthesis.

(x^2+2x+(\dfrac{2}{2})^2-(\dfrac{2}{2})^2)-7=(x+a)^2+b

(x^2+2x+1^2)-1-7=(x+a)^2+b

(x+1)^2-8=(x+a)^2+b     [\because (x+y)^2=x^2+2xy+y^2]

(x+1)^2+(-8)=(x+a)^2+b

On comparing both sides, we get

a=1

b=-8

Therefore, the value of a is 1 and the value of b is -8.
