Answer:
g(4) = 157
Step-by-step explanation:
Substitute 4 for x in g(x) = 8x^2 + 9x – 7, obtaining:
g(4) = 8(4)^2 + 9(4) - 7 = 128 + 36 - 7 = 157
Answer:
17,37
Step-by-step explanation:
one number = x
The positive number = 2x + 3
x * (2x+3) = 629
x*2x + x *3 = 629
2x² + 3x - 629 = 0
2x² - 34x + 37x - 17*37 =0
2x*(x -17) + 37(x - 17) = 0
(x - 17)(2x + 37) = 0
x - 17 = 0 ; Ignore 2x + 37 as s is a positive number
x = 17
Positive number = 2*17 +3 = 34+3 = 37
A₅=6*5-4
a₅=30-4
a₅=26
D. 26
Good Studies!!
They are not. The easiest way to tell this is by multiplying the last number of each parenthesis together. This should always result in the last number in the equation. However, -8*5 does not equal -30, so these are not the true factors.
