Answer:
B) -5, 5, -7, 7
Step-by-step explanation:
3x² - bx + 2
factor:
(3x - 2 )(x - 1) = 3x² - (5)x + 2 so 5 does work
(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work
(3x + 2 )(x + 1) = 3x² + 5x +2 = 3x² - (-5)x + 2 so -5 does work
(3x + 1 )(x + 2) = 3x² + 7x + 2 = 3x² - (-7)x + 2 so -7 does work

Answer:
Step-by-step explanation:
10x + 25y = 370
y = x + 5
10x+25(x+5)=370
10x+25x+125=370
35x=370-125
x=245/35
x=7 which is the number of dimes
x+7= 7+5= 12 which is the number of quarters
So you have 12 quarters. That means you have 7 dimes.
