Answer:
(m - 10)(m - 2)
Step-by-step explanation:
We need 2 numbers whose product is + 20 and whose sum = -12. They are -10 and -2. These go into the 2 parentheses:
(m - 10)( m - 2).
15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3
Area of a rectangle is length x width.
So the area is 15000 because 150 x 100 = 15000
