Answer:
To find the perimeter of a triangle, you would need first all three side lengths.
9.7m-6.8m = 2.9, 6.6m+6.5p=7.1, 2.2p-6.4= -4.2. once I added all the sides it was 5.8.
Divide 1200 by 1100, whatever you get from that turn it into a percentage. You may have to simplify.
Step-by-step explanation:
volume of cube = l^3
512=l^3
l=8
x=10 and x-7 is the answer
a)2x-7=13
2x=13+7
2x=20
x=20/2
x=10
b)3x+4=25
3x=25-4
3x=21
x=21/3
x=7
