Use the equation for the area of a triangle:

where A = area, h = height of the triangle, and b = base of the triangle.
You know that h=18m and A=99

. Plug those values into the equation and solve for b, the base.
The base is 11m long.

Step-by-step explanation:
here you go mate
step 1
x-6 = 5(x + 2) equation/Question
step 2
x-6 = 5(x + 2) simplify
x+(-)6=5x+10
x-6=5x+10
step 3
x-6=5x+10 subtract 5x
-4x-6=10
step 4
-4x-6=10 add 6
-4x=16
step 5

answer
x=-4
Answer: (0, 5) and (-2, 0)
<u>Step-by-step explanation:</u>
10x - 4y = -20
Let x = 0, then 10(0) - 4y = -20
-4y = -20
<u> ÷ -4 </u> <u>÷ -4 </u>
y = 5
Let y = 0, then 10x - 4(0) = -20
10x - 0 = -20
<u> ÷10 </u> <u> ÷10 </u>
x = -2
