Answer:
correct
Step-by-step explanation:
The perimeter is the sum of the sides.
Rectangle ( opposite sides are congruent ), thus
perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36
Square ( sides are congruent ), thus
perimeter = 4(x + 9) = 4x + 36
The perimeters are the same, so the student is correct
Answer:
27
Step-by-step explanation:
firstly we know we get 5 hour free so we know that when we add our total it will go up by 5. an easy way to do the equation is to take 45 and divide by two because we are essentially paying two of our 45 dollars every hour. this means that we will get half the amount we pay in hours. 45/2 =22.5 (do not round up because you will only get what you pay for and if you cant pay for a full hour you just do not get it) 22+5=27. so you get 27 hours of internet.
