(x-9) (x+2)=x²+2x-9x-18=x²-7x-18

Use distributive property: a(b +/- c) = ab +/ ac.

(x - 9)(x + 2) = (x)(x) + (x)(2) - (9)(x) - (9)(2) = x² + 2x - 9x - 18

= x² -7x -18

3 is a factor of__ A)282 B)187 C)385 D)412​
MrRissso [65]

Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7

Which expression is equivalent to 5.4+3.4w-1.8w +5.8 A) 7(1.6+w) B) 1.6(7+w) C) 1.6(7w) D) 1.6(0.25+w)
Bad White [126]
Do 5.4 plus 5.8 then do 3.4w minus 1.8w and whatever you get for each is your key to the expression. So if you were to solve the answers like A you would do 7(1.6+w) and see what you would get. Obviously A isn't the answer. Sorry, this is hard to explain. But the answer is C

X²-12x+a=(x+b)² find a and b​

Answer:

Step-by-step explanation:

x² - 12x + a = (x + b)²

x² - 12x + a = x² + 2xb + b²

-12 = 2b and a = b²

b = -6

a = b² = 36
