X² - 3x - 10
x² = x * x
10 can be factored:
1 x 10 ⇒⇒⇒ difference between factors = 9
2 x 5 ⇒⇒⇒ difference between factors = 3 ⇒ (The correct pair)
(x-5)(x+2) = x(x+2) - 5(x+2)
= x² + 2x - 5x - 10
= x² - 3x - 10
∴ x - 5 = 0 ⇒⇒⇒ x = 5
x + 2 = 0 ⇒⇒⇒ x = -2
Do you mean m*1? using that as the less then sign makes no sense here. Assuming m*1 = 100, then m=100, so 4m = 100*4 = 400
Answer:
-2x+8
Step-by-step explanation:
Hey there!
35 containers of paint
We simply divide 375 by 11, and we get 34.09..., but since we can't buy .09 of a container of paint, we can only by 35 containers of paint.
Hope it helps and have a good day!
