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
Answer:
Step-by-step explanation:
We can subtract the first equation from the second to find the value of 
, although we can also do this vice versa.
Now, we can use substitution to solve for 
:
(pick any equation for substitution)

Step-by-step explanation:
I don’t know
Answer:
2 ½ miles
Explanation:
mph = miles per hour, which means that if robert had run for the full 1 hour, he would have run 3 ⅓ miles.
however, since he only ran for ¾ of an hour, which is equal to 0.75, we can multiply the 3 ⅓ miles by 0.75 to get 2.5 or 2 ½ miles.
i hope this helps! :D
Answer:
Step-by-step explanation:
They are also similar.
Both have 4 right angles. Both have 2 sets of parallel lines. Both have 4 equal sides.
But I think you are supposed to answer if figure 1 is similar to figure 2 and figure two is similar to figure 3 then by the transitive property, figure 1 is similar to figure 3.
