Step-by-step explanation:
thanks for the points loser
the answer for the first one is 15
Step-by-step explanation:
the length of the rectangle is 18 and there are 6 squares in the horizontal lines so the length of each square is 18÷6=3.
there are 5 squares in the vertical line so the width is 3*5=15
Answer:
Equations:
3c + 4m = 12.50
3c + 2m = 8.50
-----------------------
Subtract and solve for "m"::
2m = $4

Answer:
x = 2 ±
Step-by-step explanation:
Given
y = x² - 4x - 9
To find the zeros, set y = 0, that is
x² - 4x - 9 = 0 ( add 9 to both sides )
x² - 4x = 9
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(- 2)x + 4 = 9 + 4, that is
(x - 2)² = 13 ( take the square root of both sides )
x - 2 = ± ( add 2 to both sides )
x = 2 ± ← exact solutions
