I know that x + 2 is a factor of P(x) = 2x^{3} + 5x^{2} + 5x + 6, but I just don't know how to do the second half

explain it again

Step-by-step explanation:

i don't understand

Given: 160.5 in²=area of paralellogram

           7.5 in = height

            b = ?

Let us work out for the missing base. Basically, the formula in finding the area of a parallelogram is A= b × h. Since base is missing, we will use b= A/h where, area is divided by the measure of the height. 

so, 

 b= A/ h

  = 160.5 inch² ÷ 7.5 inch

  = 21.4 inch

Therefore base has the measure of 21.4 inches. 

Check:

A= b × h

 = (21.4 inch)(7.5 inch)

A= 160.5 inches²
