Answer:
687.5
Step-by-step explanation:
To find the equivalent expression, simplify the operations using order of operations.
2.50(600 - 500*.25) - 500 Multiply -500*0.25
2.50(600 - 125) - 500 Subtract 600 - 125
2.50(475) - 500 Multiply 2.50(475)
1187.5 - 500 Subtract
687.5
Answer:
A
Step-by-step explanation:
you can find the vertex of each equation and then compare to the graph
x = -b/2a
A) x = -(-9)/2(1); x = 9/2 or x = 4 1/2
plug 4 1/2 into equation as 'x' to find 'y'
y = (9/2)² - 9(9/2) + 20
y = 81/4 - 81/2 + 20
y = 81/4 - 162/4 + 80/4
y = -81/4 + 80/4
y = -1/4
the only option with a vertex at (9/2, -1/4) is A

Answer:
The area is 1,014 cm^2
Step-by-step explanation:
Here, we want to find the total surface area of a cube with side length of 13 cm
what we shall do here is to apply the formula to get the total surface area
Mathematically, that will be
A = 6L^2
so we have
Area = 6 * 13^2
Area = 1,014 square cm
