Answer:
(3 - x)(3 + x)(2x + 1)
Step-by-step explanation:
18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )
= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term
= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )
= (3² - x²)(2x + 1)
= (3 - x)(3 + x)(2x + 1)
This is problem #9. I'm not sure how to solve #10, although the solution may be found in a similar way.
-10p - (1-2p)
(Multiply (1-2p) by -1)
-10p - 1 + 2p
(Combine like terms)
-8p - 1
ANSWER: -8p - 1
Answer:
20
Step-by-step explanation:
If x = 6 the problem should look like this:
2 (x) + 8 = y -> place the 6 where x is.
2 (6) + 8 = y -> remember () means to multiply.
2 times 6 , add 8 , equals y
12 + 8 =y -> 12 +8 equals 20
20 = y
I hope this helps!!
