Answer:
p = 7
Step-by-step explanation:
(x² + px - 3)(3x - 5)
each term in the second factor is multiplied by each term in the first factor, that is
x²(3x - 5) + px(3x - 5) - 3(3x - 5) ← distribute parenthesis
= 3x³ - 5x² + 3px² - 5px - 9x + 15 ← collect like terms
= 3x³ +x²(3p - 5) - x(5p + 9) + 15
given the coefficient of the x- term is - 44 , then
-(5p + 9) = - 44 ← - (5p + 9) is th coefficient of x in the expansion
- 5p - 9 = - 44 ( add 9 to both sides )
- 5p = - 35 ( divide both sides by - 5 )
p = 7

Answer: 30
Step-by-step explanation: If she has 6 on one side, the that would mean there is 6 on at least 1 other side. And to make up for the remaining 10 feet or trim, we would get 5 and 5. So her quilt is 6x5 and we can use that equation to get the number of blocks, too. So 6x5=30.
7 is the slope intercept form of this equation. i hope this helps.
