Answer:
1. A=42
L=14
42=W(14)
divide both sides by 14
3=W
2. A=96
L=12
96=W(12)
divide both sides by 12
8=W
3. A=90
L=18
90=W(18)
divide both sides by 18
5=W
4. A=1.50
L=15
1.50=W(15)
divide both sides by 15
0.1=W

Answer:
Step-by-step explanation:
The area of a triangle with height 
and base 
is given by 
. By definition, the base and the height must intersect at a 90 degree angle. Therefore, the diagram gives a base of 14 cm and a height of 8 cm. Substituting these values, we get:
X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
