Answer:

C. 210 miles.

Step-by-step explanation:

If Car 1 left 30 minutes earlier

than Car 2 therefore Car 2 traveled 3 hours

compared to Car 1's 3.5 hours

Car 1 traveled 3.5 x 42 mph = 147 miles

Car 2 travelled 3 x 50 mph = 150 miles

The distance between them would be  

√147^2 + 150^2

= 210

What values of b satisfy 3(2b + 3)2 = 36?
alexira [117]
To find the answer, you need to solve for b.

2(2b + 3) = 12  divide both sides by 3
2b + 3 = 6  divide both sides by 2
2b = 3  subtract 3 from both sides
b = 1.5  divide both sides by 2

b = 1.5 satisfies the equation. if you plug 1.5 in, you get that the equation is true.
