Use the Pythagorean Theorem to find the length of the side marked "x."
x^2 + (10 mi)^2 = (13 mi)^2. Thus, x^2 + 100 mi^2 = 169 mi^2.
Next, x^2= (169-100) mi^2, or x^2 = 69 mi^2. Find the positive square root of both sides of this equation. What is it?

the formula of that is (x,y). you would need to go 8 to the right and 5 units up. sophie mixed up the values.
Answer:
200
Step-by-step explanation:
If there are 2 squares next to eachother with the same area, then their perimeter is 6*sidelength.
60 = 6*sidelength
10 = sidelength
Square the sidelength to find the area of the square. 10^2 = 100
Multiply that by 2 to find the area of the rectangle. 100*2 =
200
Answer:
7x+6 = 5(x+6)
Step-by-step explanation:
x represents Harry's age now, so 7x represents Nick's age now. (Nick is 7 times as old as Harry.)
In 6 years, Harry's age will be x+6.
In 6 years, Nick's age will be 7x+6, which is 5 times Harry's age at that time, 5(x+6). Hence an appropriate equation is ...
... 7x+6 = 5(x+6)
_____
Please note that finding the value of x does not give the answer to the question. We are asked for Harry's age in 6 years, so the answer is x+6 (=18).
