Assume L=1.5W, where W=width, L= Length of the triangle.
Therefore,
Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in
Then, L=1.5W = 1.5*4 = 6 in
Area, A= L*W = 6*4 = 24 in^2
-3|2x + 6| = -12
|2x + 6| = -12/-3 = 4
2x + 6 = 4 and 2x + 6 = -4
2x = 4 - 6 = -2 and 2x = -4 - 6 = -10
x = -2/2 = -1 and x = -10/2 = -5
x = -1 and x = -5
Answer:
The answer is 5.9
Step-by-step explanation:
1) Subtract 31.7 from both sides.

2) Simplify 14 - 31.7 to -17.7

3) Divide both sides by -3.

4) Simplify -17.7/-3 to 5.9

5) Switch sides.

Therefor, the answer is x = 5.9.
Answer:
3n - 4
Step-by-step explanation:
for "four less than three times a number" meaning you subtract 4 from the product of 3 and the unknown number.
12c² = 3c² · 4
15c³ = 3c² · 5c
LCM(12c²; 15c³) = 3c² · 4 · 5c = 60c³
