8) Onaje is correct
9a) answers could be: 3(6y) or 4y + 6y + 8y or 2(2y + 3y + 4y)
b) all answers simplify to be 18y
Step-by-step explanation:
Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t
16t + 9t only equals 25t

Answer:
1. P = 44 A = 75
2. P = 30 A = 28
3. P = 20.9 A = 24.25
Step-by-step explanation:
1. To find the perimeter of a parallelogram, you add the length of all four sides. We know that parallelograms have two pairs of equal sides, so in this particular case, two sides are 15 cm and two are 7 cm. 15+15+7+7=44. To find the area of a parallelogram, you multiply the base by the height. The base of the parallelogram is 15 cm and the height is 5 cm. 15*5=75.
2. To find the perimeter of a triangle, you add the length of all three sides. 14+9+7=30. To find the area of a triangle, you multiply its base, its height, and 1/2. This triangle has a height of 8 and a base of 7. 8*7*1/2=28
3. To find the perimeter of a trapezoid, you add the length of all four sides. 5+3+6.2+6.7=20.9. To find the area of a trapezoid, you add the two bases, divide by two, and multiply by the height. This trapezoid has two bases that measure 3 ft and 6.7 ft. 3+6.7=9.7. 9.7/2=4.85. This trapezoid has a height of 5 ft. 4.85*5=24.25
