a trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120

so the area is 120cm

A trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42

So the answer is 42 inches

A kite

equation for area = p× q ÷ 2

so you sub that in

(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3

So the answer is 33 cm

9x-7=-7 how do you solve this problem

borishaifa [10]

<span>9x-7=-7
You would add 7 to both sides because you want to get to the point were your variable is alone. 9x = 0 Then you would dicide each side by 9 because after doing this your variable would be alone. x = 0 would be your final answer.

Answer:

x < -11/6.

Step-by-step explanation:

−12x + 13 > 35

-12x > 35 - 13

-12x > 22

Divide both sides by -12 and invert the inequality sign:
