Step-by-step explanation:
A
2x3 is 6x4 is 24+5 is 29
B
6+20 is 26
C
9x5 is 45
D
6+8 is 14x5 is 70
SO THIS MEANS THAT B IS YOUR ANSWER

Answer:
It's like solving a quadratic, but in reverse, and in this case you'll arrive at x2+x−12=0
Explanation:
We're going to go "backwards" with this problem - normally we're asked to take a quadratic equation and find the roots. So we'll do what we normally do, but in reverse:
Let's start with the roots:
x=3, x=−4
So let's move the constants over with the x terms to have equations equal to 0:
x−3=0, x+4=0
Now we can set up the equation, as:
(x−3)(x+4)=0
We can now distribute out the 2 quantities:
x2+x−12=0
Answer:
24 hr × 30% = 24 hr × 0.30 = 7.2 hr (or 7 hr 12 min)
