X=55 .................................................................
Answer: H
Step-by-step explanation:
We can see this rectangular prism will have side lengths of 5, 3, 7.
So we can use the fact Surface Area = 2(lh+wh+lw) to get:
2(15 + 35 + 21) = 2(71) = 142
The answer is <span>20.4833333</span>
DIVIDE EVERYTHING BY 5 ==>x²+6x+y²=3
complete the square of x²+6x ===> x² + 6x + 9 - 9 ===>(x+3)²2 - 9
===>(x+3)² - 9 + y² = 3===>(x+3)² + y² = 12 this is the equation
Answer:
It is also useful because we can read the slope and y-intercept from the equation
