Answer:
Step-by-step explanation:
The vertex form of an equation of a parabola:
(h, k) - vertex
We have
We must use the formula:
Use the distributive formula a(b + c) = ab + ac
Answer:
23
Step-by-step explanation:
2x+14+x+7=90, 3x+21=90,3x=90-21. 3x=69, x=23
18-6=12
2/3=0.66
12/0.66=18.1
18 is the answer
5 times 3 equals 15 so they gained 15 yards. 12 times 2 equals 24. 24 minis 15 equals 9. So the answer in 9 yards
X/5+9=4
Subtract each side by 9
X/5=-5
Multiply each side by 5
X=-25
