Answer:
Step-by-step explanation:
2x² + 9x = -7
2x² + 9x + 7 = 0
When we multiply we should get 2*7 = 14 and when we add we should get 9. Find the factors of 14 ---> 1,2,7,14. Factors are 2,7 as when we multiply we get 14 and we we add, get 9
2x² + 2x + 7x + 7 = 0
2x( x + 1) + 7 (x + 1) = 0
(x + 1)(2x + 7) = 0
Answer:
if im not wrong its c? you have to take √2 of 4√2 which makes 8...
Answer: x = 8
Step-by-step explanation:
9 ( x - 3 ) = 45
distribute 9
9x - 27 = 45
combine constants
9x = 45 + 27
compute 45 + 27
9x = 72
divide both by 9
9x/9 = 72/9
final answer
x = 8
Answer:
slope = 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (3, 8)
m = = = 3
