0=x^2+4x+1. Khan academy

Now, to find 'x' you will apply the Null Factor Law. This means you will now let 'x' = 0, and simply move the -2 over to the other side to find your answer. Note: since we are using a perfect square, x will only have one value since there is only one answer (x-2) in the brackets, meaning in this case we can ignore the exponent (as the answers will be the same). If there was more than one answer in the bracket (e.g. (x-4) and (x-6)), then we would apply Null Factor Law to both brackets and solve for x.

(x−2)=5

x=5+2

x=7

a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the pri
laiz [17]

For this case we have that the surface area of the prism is given by:

SA = A_ {l} + 2B

Where:

A_{l}: Is the lateral area

B: It is the area of the base

A_ {l} = P.h

Where:

Q: It is the perimeter of the base

h: It's the height

A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2

On the other hand:

B = 12 * 8\\B = 96 \ in ^ 2

So, we have:

SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2

Answer:

SA = 352 \ in ^ 2
