Answer:
Perimeter =
feet
Area = 60 feet²
Step-by-step explanation:
Let us revise the rules of perimeter and area of a rectangle
- Perimeter = 2(Length + width)
→ From the given figure
∵ The length =
feet
∵ The width = 5
feet
→ Simplify the roots
∵ 
∴ 
∴ The length =
feet
∵ 
∴ 
∴ The width =
feet
→ Perimeter = 2(Length + width)
∵ Perimeter = ![2[2\sqrt{2}+15\sqrt{2}]](https://tex.z-dn.net/?f=2%5B2%5Csqrt%7B2%7D%2B15%5Csqrt%7B2%7D%5D)
∴ Perimeter = ![2[17\sqrt{2}]](https://tex.z-dn.net/?f=2%5B17%5Csqrt%7B2%7D%5D)
∴ Perimeter =
feet
→ Area = Length × Width
∵ Area =
× 
∴ Area =
∴ Area = 60 feet²
Y<-1/2x
Y> or = -1
Because if you plug in a number then it's the only one that fits
First one is c and second one is 6.2 x 10^1
Answer:
PT = 17
Step-by-step explanation:
Since T is the midpoint of PQ, then
PT = TQ , substitute values
4x + 5 = 8x - 7 ( subtract 4x from both sides )
5 = 4x - 7 ( add 7 to both sides )
12 = 4x ( divide both sides by 4 )
3 = x
Thus
PT = 4x + 5 = 4(3) + 5 = 12 + 5 = 17
