Step-by-step explanation:
in this case its addition , but the only reson it is going first is bc it sin the parenthasies
Answer:
the first one
1, 2, 3, 4, 6, 9, 12, 18, 36
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
