Step-by-step explanation:
Answer:
10
Step-by-step explanation:
a^2 + b^2 = c^2 (Pythagorean Theorem)
The length is 8(a)
The width is 6(b)
C is the unknown
8^2+6^2 = 100
then you need to square root the 100

This is an arithmetic series with common difference 6
S13 = (13/2)[2*-5 + (13-1)*6)] = 403
Answer:
C
Step-by-step explanation:
1. Add 4x +8
the awswer would be 12x
2. subtract the 12x from the lenght which is 24
then your and will be 12
Answer:
you may have done this wrong
Step-by-step explanation:
5x-3=121
add 3 on both sides
5x=-36<------what you did was wrong
you should have ended up with...
5x=124
divide by 5 on both sides
x=24.8
