Answer:
A) 5
Step-by-step explanation:
(7 + 1)( 7+ 2) 7 + 1
First positive number (x) = x
Second positive number (y) = x+3
Product: 180 = x · y
180 = x · (x + 3)
180 = x² + 3x
0 = x² + 3x - 180
0 = (x + 15)(x - 12)
0 = x + 15, 0 = x - 12
x = -15, x = 12
x = -15 is NOT a positive number so it can be disregarded.
Answer: 12

Answer:
c = 
Step-by-step explanation:
Given
x² - x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - x
x² + 2(-
)x + 
= (x -
)² ← a perfect square
with c =
