Answer:
132un^2
or 132 units squared
Step-by-step explanation:
I'm going to solve for the areas of all three shapes separately and then add them together.
Triangle 1:
6 * 8 * 0.5 =
24
Rectangle:
12 * 8 =
96
Triangle 2:
8 * 3 * 0.5 =
12
All of them together:
24 + 96 + 12 =
132
Answer:
Kimberly and Mike had at first $100 each
Step-by-step explanation:
Assume that Kimberly and Mike each have $x
∵ Kimberly has $x
∵ Kimberly spent $50
- Find the reminder with Kimberly by subtracting 50 from x
∴ The money left with Kimberly = x - 50
∵ Mike has $x
∵ Mike spent $25
- Find the reminder with Mike by subtracting 25 from x
∴ The money left with Mike = x - 25
∵ Mike's money is 50% more than Kimberly's money
- That means Mike's money is more than Kimberly's money by
50% of Kimberly's money
∴ x - 25 = (x - 50) + 50%(x - 50)
∵ 50% = = 0.5
∴ x - 25 = (x - 50) + 0.5(x - 50)
- Simplify the right hand side
∴ x - 25 = x - 50 + 0.5x - 25
- Add the like terms in the right hand side
∴ x - 25 = 1.5x - 75
- Add 75 to both sides
∴ x + 50 = 1.5x
- Subtract x from both sides
∴ 50 = 0.5x
- Divide both sides by 0.5
∴ 100 = x
∵ x represents the amount of money that Kimberly and
Mike each had at first
∴ Kimberly and Mike had at first $100 each
Answer:
Step-by-step explanation:
F(x)=x³-27/x²-9
F(x)=(-9)³-27/(-9)²-9
F(x)=-729-27/-81-9
F(x)=-756/-90
F(x)=42/5
