Answer:
a = 33ft
b= 66ft
c = 48 ft
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- a (shortest side)= a
- b (second side)=2a (twice the length of the shortest side)
- c (third side)= a+15 ( 15 feet more than the length of the shortest side)
Since:
Perimeter = a+b+c
Replacing with the values given:
147 = a+2a+(a+15)
147 = a+2a+a+15
147-15 = a+2a+a
132 = 4a
132/4 = a
33 ft= a
Substituting a =33 in the other expressions:
b=2a = 2(33) = 66 ft
c= a+15 = 33+15 = 48 ft
The answer is 69 , because it just cancels out the numbers
Answer: 1/51
Step-by-step explanation: 1/51 is cut into bigger pieces. Its like cutting 2 pizza's of the exact same size. If you cut one into 5 pieces and another one into 10. If you take a piece of pizza out of both pizza's then the one cut into 5 pieces would be a ligger size.

Answer: 
a = 2 and b = 3
==================================================
Explanation:
Let's expand out 
to get the following:
The x term here is 2ax
Compare this to the x term of 
and we see that
--------------
The constant term of 
is the 
portion since it doesn't have the variable x attached to it.
Compare this with the 7 of which is also the constant.
Equate the two items, plug in a = 2 and solve for b.
Therefore,
