Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
Answer:
8
Step-by-step explanation:
you solve this by reversing the excercise.
17 + 7 = 24
24/3 = 8

Answer:
A
Step-by-step explanation:
30 minutes = half an hour
Carly:
450/2 = 225
620/2= 310
225 + 310 = 535
Carly burned 535 calories total
Sarah:
560/2 = 280
510/2 = 225
280 + 225 = 505
Sarah burned 505 calories total
Carly burned more calories than Sarah
Answer:
-3
Step-by-step explanation:
There are two ways to see what the next sequence number would be in this case.
First approach, you start with the first number (1) than count every other number, which are all positive integers. You do the same starting from the second number (-1), which would then be all negative integers.
Second approach, consider 2 consecutive numbers being a single element of the series... each has a number (1,2,3) with its positive and negative values.
