Our x equals 0 so the answer is 0
Answer:
64
Step-by-step explanation:
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
I need a picture to answer your question
5x1.50 = 7.5
2x3 = 6
7.5 + 6 = 13.5
Change Travis will recieve
= 20 - 13.5
= $6.5
