<span>The square is equal so all sides have equal sides. Soooo...
s2 (s squared) + s2 = 15 (squared)
15 x 15 = 225
225/2 = 112.5
Now you just have to get the square root. So go onto ur calculator. Which equals 10.606

Y=10
explanation:
-4•2= -8
2•4=8
-8+8=0
y=10
The answer is B because -3 -8 = -11.
Answer:
s=42
Step-by-step explanation: 126 divided by 3 = 42
42mph
Let the slower cars speed equal X.
The faster cars speed would be X+5 ( 5 mph faster).
They traveled for 3 hours
Multiply the time of travel by speed to equal the number of miles traveled.
So you have:
3X + 3(X+5) = 267 miles
Simplify the left side:
3X + 3X+15 = 267
Combine like terms:
6x + 15 = 267
Subtract 15 from each side"
6x = 252
Divide each side by 6:
x = 252 / 6
X = 42
The slower car was traveling at 42 mph and the faster car was traveling at 47 mph.
