Answer:
Step-by-step explanation:
so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.
Equation:
(x+3x-4)*2=72
(4x-4)*2=72
8x-8=72
8x=80
x=10
length:10
width:26
Lets break this down here.
First- 198 rounded would be 200
Then- we add 727 which would be 927
if you were to round that it would be 930
Answer:
6 and 1/3
Step-by-step explanation:
the only thing gets reduced is the fraction part and 5 and 15 have common numbers in 5 5 goes into 5 one time and 5 goes into 15 3 times. so it's 6 1/3
Find the GCF, then factor it out. Finally, simplify each term in the parentheses.
5x + 2x3 + 8x2
