15 is 9 more than j.
Zina [86]

Answer:

j = 6

Step-by-step explanation:

"Is" typically means equals. "More than" means it is added to.

So 15 equals j with 9 added to it.

15 = 9 + j

Now solve for j by subtracting 9 from both sides.

15 - 9 = j

j = 6

just olya [345]

Answer:

253cm²

Step-by-step explanation:

Area of the trapezoid = 1/2(b1+b2)*h

Given

h = 22cm

b1 = 10.5cm

b2 = 12.5cm

Substitute

Area of the trapezoid = 1/2(10.5+12.5)*22

Area of the trapezoid = 1/2(23)*22

Area of the trapezoid =11*23

Area of the trapezoid = 253cm²

Hence the area of the trapezoid is 253cm²
