The answer is −10d4+17d2s−6s2
I believe the answer would be 90.
FOIL is an 'acronym'. It helps you remember how to multiply
two binomials ... like (2x-7) and (5x+5) .
FOIL stands for "First, Outside, Inside, Last". Here's how it's used
to multiply these particular two binomials:
(2x - 7) (5x + 5)
First: (2x) (5x) = 10x²
Outside: (2x) (5) = 10x
Inside: (-7) (5x) = -35x
Last: (-7) (5) = -35
Add them all together, and you have the product:
10x² + 10x -35x -35
Simplify the sum: 10x² - 25x -35
or 5(x² - 5x - 7) .
The answer would be -6 because -5+1 =-4 then once you divide it by 2 you get -2 then you do the next part 3-7 because since it’s in those lines that means you get rid of the negative so you would get -4 so the equation should look like this by now -2-4 then solve and you get -6 hope this helped :)
Answer:
-36
Step-by-step explanation:
-9 - 2(p + 11)2- 7
-9 - 2(-6 + 11)2- 7
-9 -2 * 5*2 -7
-9 -10*2-7
-9 -20 -7
-36
