7n^2 + 5 = 453
Subtract 5 from both sides:
7n^2 = 448
Divide both sides by 7:
N^2 = 64
Take the square root of both sides:
N = 8
Answer:
Step-by-step explanation:
perp: 1/4
y - 4 = 1/4(x + 12)
y - 4 = 1/4x + 3
y = 1/4x + 7
answer is C
Answer:
x=122/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(x+1)(3)−10=740
18x+18+−10=740(Distribute)
(18x)+(18+−10)=740(Combine Like Terms)
18x+8=740
18x+8=740
Step 2: Subtract 8 from both sides.
18x+8−8=740−8
18x=732
Step 3: Divide both sides by 18.
18x
