Mathematics

5 0

Answer:

x=3

Step-by-step explanation:

You have to do the opposite of the operation to get the like terms on the same side of the equation sign. You have to add 22 to 29 (you add because its originally subtracted, or negative) and you add 7x to 10x. Then divide 51 by 17x giving you 3.

A parallelogram has an area of x^2 + 9x - 36. A. What are expressions for the length and width of the parallelogram?B. If x is a

katrin2010 [14]

Step-by-step explanation:

$Area \: of \: parallelogram \\ = {x}^{2} + 9x - 36 \\ = {x}^{2} + 12x - 3x - 36 \\ = x(x + 12) - 3(x + 12) \\ = (x + 12)(x - 3) \\ \implies \\ length = (x + 12) \: units \\ width = (x - 3) \: units \\$

For this parallelogram to exist least value of x should be 4.

Because if x = 3

(x - 3)= 3 - 3 =0

Thus width of parallelogram would become zero as a result area of parallelogram would become zero i. e. Parallelogram won't exist.
