Height x Width = Area
Area divided by height = Width
31.5 divided by 6.3 = 5ft
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
divide both sides by 7 to get x alone
84/7 = 12
B.12
D. 13. Because 3-(-5)= 8. And -13-(-5)= 8
4n-5=3n+2
subtract 3n from each side
4n -5 -3n = 3n +2 -3n
n -5 = 2
add 5 to each side
n-5+5 = 2+5
n = 7
To solve a equation with a variable, you need to get the variable alone. I got the variable on the left hand side and the constants on the right hand side
