Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
2x-438 = -438+2x= 2(x-219)
And....?
There's not enough info for me to answer.
Answer:
B
Step-by-step explanation:
First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial
. We can now use the quadratic formula to solve.
Remember that the quadratic formula is

Substitute the numbers from the equation into the formula.

Simplify:


Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with
.
Hope this helps!
