Solve for m:
8 = m/4

8 = m/4 is equivalent to m/4 = 8:
m/4 = 8

Multiply both sides of m/4 = 8 by 4:
(4 m)/4 = 4×8

(4 m)/4 = 4/4×m = m:
m = 4×8

4×8 = 32:
Answer: m = 32 thus m - 12 = 32 -12 = 20

Answer:

$= > in \: the \: bigger \: triangle \\ height = 14 \: ft \\ base = 22.5 \: ft \\ = > in \: smaller \: triangle \\ height = x \: ft \\ base = 9 \: ft \\ using \: ratios \\ \frac{bigger \: height}{smaller \: height} = \frac{bigger \: base}{smaller \: base} \\ \frac{14}{x} = \frac{22.5}{9} \\ \frac{14}{x} = 2.5 \\ x = \frac{14}{2.5} \\ x = 5.6 \: ft$

What us the length of the longer side?

julsineya [31]

The perimeter:
$P=2\cdot(3x+3)+2\cdot2x=6x+6+4x=10x+6\\\\P=146\ units\to10x+6=146\ \ \ |-6\\\\10x=140\ \ \ |:10\\\\x=14\ units$
The length of the longer side:
$3x+3=3\cdot14+3=42+3=45\ units$
