Use the distributive property: a (b + c) = ab + ac
(3x² + 2x - 5) (2x - 3) = 3x² (2x - 3) + 2x (2x - 3) - 5 (2x - 3)
... = (6x³ - 9x²) + (4x² - 6x) + (-10x + 15)
... = 6x³ - 5x² - 16x + 15
Answer:
y = 4x + 5
Step-by-step explanation:
slope = m = 4
y-intercept = b = 5
y = mx + b
y = 4x + 5
Answer:
21
Step-by-step explanation:
3 x 7 is 21
Answer:
Option B) The variable Y will cancel out first.
Step-by-step explanation:
we have
5x-y=-21 ----> equation A
x+y=-3 ----> equation B
Solve by elimination
Adds equation A and equation B
5x-y=-21
x+y=-3
--------------
5x+x=-21-3 ----->variable y will be eliminated first
6x=-24
x=-4
Answer:
c
Step-by-step explanation:
you have a calculator dont you?
