Answer:
In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.
The full correct process is:
(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15
= 4m - 6m + 9 + 15
= -2m + 24

Answer:
x = 12
Step-by-step explanation:
For the middle size triangle
short leg = x
long leg = (25 - 9) = 16
ratio = x/16
For the small triangle
short leg = 9
long leg = x
ratio = 9/x
Similar triangles are proportional so
Set the ratios equal
x/16 = 9/x
Cross multiply
x² = 144
Take the square root of both sides
x = 12
