Answer: A
Explanation:
First you have to write the model in an equation form.
6x+5=15
Subtract 5 from both sides
6x=10
Divide 6 from both sides
X=10/6
Simplify
X=5/3 or 1.67
Subtract 4 from both sides, solve using quadratic formula
ax^2+bx+c
(-b(+or-) Square Root of b^2 - 4ac)/2a
9x^2+9x-4=0
-9(+or-)Square root of 9^2-4(9)(-4)/2(9)
Solve^
