Answer:
x = 32
Step-by-step explanation:
Add 7 to both sides
Simplify
-7 + 7 = 0 and 1 + 7 = 8 because of this now 
Square both sides
2x = 64
Slove 2x = 64
64 ÷ 2 = 32 = x
Answer:
2√(5)
Step-by-step explanation:
Since it's stated that thegiven is right triangle :
The square length of hypotenus (the side lenght that sees 90 degrees) is equal to sum of square length of side lengths
2^2 + 4^2 = x^2
4 + 16 = x^2
20 = x^2 and x = 2√(5)
Answer:
Sooo it can complete 120 laps in 1 hour.
40/8=5
$5= 1gal.
5x10=50
So 10 gallons of gas costs $50
