Answer:
15 feets
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets
Your question is missing some elements but to answer the question I have to make an assumption.
Assuming that she make a
monthly payment of $75.
The value of an loan at the end of the two year is given by

where PV = $799, r = 7.2% = 0.072 and n = 2 years.
Thus,

If she makes a monthly payment of $75, the number of months it will take her to pay off for her laptop is given by

Therefore, it will take her 13 months to pay off for the laptop.
1 mile = 1.6 kilometers
multiply 40 mph by 1.6 = 64
car's rate = 64 kilometers per hour
multiply kilometers per hour by 4 = 256
car will travel 256 kilometers in 4 hours

Step-by-step explanation:
Answer:
the first one
the third one
the fourth one
Step-by-step explanation:
1. x <em>does</em> equal 9
2. the equation would lead to x being canceled out so there would be an x in your answer
3. x <em>does</em> equal 30
4. x <em>does</em> equal 6
5. x should equal 135
