Answer:
The answer to the question is2,592 square feet
Answer:
Step-by-step explanation:
total cost = unit cost times number purchased:
total cost = ($0.50/banana)(7 bananas) = $3.50 for 7 bananas
X² - 8x = -10
to have a complete square, we must have this format:
a² + 2ab + b²
a² = x²
2ab = -8x ⇒ 2(x)(-4)
b² = -4² = 16
x² - 8x + 16 = -10 + 16
x² - 8x + 16 = +6
(x-4)² - 6 = 0
Both sides must have an additional value of 16.
Answer:
67.5
Step-by-step explanation:
If all triangles equal 180 degrees, and one angle is 45 degrees, you get the equation 180 = 45 + x + x which is the same as 180 = 45 + 2x, and instead of that equation, you can use 180 - 45 = 2x. That gives you 135 = 2x, and now divide both sides by 2 and you get 67.5 = x
Answer:
7(45)=7(40)+7(5)
Step-by-step explanation:
We need to represent 7(45) using the distributive property to simplify.
We can write 45 as 40+5
So it becomes,
7(45) = 7(40+5)
Distributive property is : a(b+c)=ab+ac
a=7, b = 40 and c = 5
7(40+5)=7(40)+7(5)
So, the correct option is (4).
