Which equation has no solution?
4(x + 3) + 2x = 6(x + 2)
5+2(3 + 2x) = x + 3(x + 1)
5(x + 3) + x = 4(x + 3) + 3
4 + 6(2 + x) = 2(3x + 8)
O

Step-by-step explanation:

4(x+3)+2x = 6(x+2)  →   4x +12 +2x = 6x + 12 → No solution

5 + 2(3+2x) = x + 3(x+1)  →  5 + 6 + 4x = x + 3x + 3 → No solution

5(x + 3) + x = 4(x+3) + 3 → 5x + 15 + x = 4x +12 +3 → 6x + 15 = 4x + 15 → x= 0

4 + 6(2+x) = 2(3x +8)  →   4 + 12 + 6x = 6x + 16  → No solution

2x^2+5x+17

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
