Answer:
Sorry if i am wrong but i am pretty sure it is d≈3.82
Step-by-step explanation:
Ok. Firstly, we solve 5÷5=1. Next, we take 1 and multiply that by 7 which is 1×7=7. Lastly we take that and add one to it which is 7+1=8. Hence, our answer is 8.
Answer:
Dimensions are 20 X 44 feet
Step-by-step explanation:
First we need to build two equations:
For area X times Y = 880
For Perimeter 2x + 2y = 128
Now we need to solve one so we can substitute it into the other:
2x + 2y = 128 becomes
2x = 128 - 2y and then
x = 64 - y We will substitute this into the are equation
(64 - y)y = 880
64y -
= 880
-
factor out the negative
-(
Factor:
-(y - 20)(y - 44) = 0
y-20 = 0 and y - 44 = 0
y = 20 and y = 44
Plugging these in two both of our formulas works
20 X 44 = 880 for area
2(20) + 2 (44) = 128 for perimeter
