Answer:
-3p - p²
Last option
Step-by-step explanation:
Step 1: Write out expression
2p - 7p² - 5p + 6p²
Step 2: Combine like terms (p²)
-p² + 2p - 5p
Step 3: Combine like terms (p)
-p² - 3p
Step 4: Rewrite
-3p - p²
Answer:
25
Step-by-step explanation:
If it gives a result of -4 then our equation will have .... = -4
If we subtract 9 from the quotient of a number and 5 we have x/5 - 9
Our equation is:
x/5 - 9 = -4 add 9 to both sides
x/5 = -4 + 9
x/5 = 5 multiply both sides by 5
x = 5(5)
x = 25
Check: 25/5 - 9 = 5-9 = -4
Answer checks as correct from information given
(y -3)^2 = 4y - 12
Expand.
(y-3)(y -3) = 4y - 12
y² - 6y + 9 = 4y - 12
y² - 6y -4y + 9 + 12 = 0
y² - 10y + 21 = 0
Factors are -7y and - 3y
y² - 10y + 21 = 0
y² - 3y - 7y + 21 = 0
y(y - 3) -7(y - 3) = 0
(y - 3)(y - 7) = 0
y-3 = 0 or y - 7 = 0
y = 0 + 3 or y = 0 + 7
y = 3 or 7
