Answer

10

15

20

25

Answer 1

area = 1/2(base*height)

Answer 2

just take an answer minus it by 5 and multiply the number you get with the answer and apply it to the formula dumbcow put up there

Answer 3

---> 75 = 1/2( (height-5)*height)

solve for height

Answer 4

yea there

Answer 5

you have to use factoring a quadratic

Answer 6

Let x = height

--> x(x-5) = 150

x^2 -5x -150 = 0

solve by factoring

what 2 num add to -5 but mult to -150 ??

Answer 7

would my final answer be 15?

Answer 8

that is correct :)

Answer 9

x^2 - 5x -150 = (x-15)(x+10) = 0

x = 15 or -10

height must be positive therefore
x=15
