Answer:
x = -4 and x = 2
Through the Completing the Square process below:
Step-by-step explanation:
solve 6x^2 +12x-48=0
first divide out the 6
x^2 + 2x - 8 = 0
Then use the Diamond method:
-8 = -2*4 , and -2 + 4 = 2
so
x^2 - 2x + 4x - 8 = 0
x(x - 2) + 4*(x -2) = 0
(x + 4)(x - 2) = 0
so, solve x + 4 = 0 and (x - 2) = 0
x = -4 and x = 2
<u>Answer:</u>
Beto will get to the school first.
<u>Step-by-step explanation:</u>
We are given that Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile.
So Delia takes

While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.
So Beto takes
10.5 minutes to reach school.
Therefore, Beto will get to the school first.
