Hi! does the problem give any numbers
F(t)= $100 x h + 300 A reasonable domain is (1,2,3) and the range is ($400,$500,$600)
I think that the answer is 16
The of the first multiples of 21 is 21, 42, 63, 84, 105
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
