Answer:

92.5

Step-by-step explanation:

Lets say, first number = x

Second number = 3x+7

Total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

3x+7 = 3(10.5)+7 = 92.5

Which of the following correctly completes the square for the equation below? X^2-5x=0

Mumz [18]

In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4

x² - 5x + 25/4 = 25/4

completes the square:
(x - 5/2)² = 25/4
