Answer:
4s+14t
Step-by-step explanation:
2*[(s+5t)+(s+2t)]
=2*(2s+7t)
=4s+14t
Remark
The Perimeter of a rectangle is found using
P = 2L + 2w
Givens
L = s+2t
w = s + 5t
Solution
P = 2(s + 2t) + 2(s + t5) Remove the brackets
P = 2s + 4t + 2s + 10t Combine
P = 4s + 14t
Answer P = 4s + 14t This cannot be reduced any further.
999 divided by 9 is 111
76%
Times the decimal by 100 to get a percent
basically moving the decimal 2 spaces to the right.
Its B
1^3 is 1
Subtract 2/3 from both sides.
