Answer:

x = -11

Step-by-step explanation:

Add 9 to both sides of the equation

3 − 9 = −42

3 − 9 + 9 = −42 + 9

Simplify

Add the numbers

3 = −33

Divide both sides of the equation by the same term

3 = −33

3/3 = −33/3

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

= −11

Find the area of the triangle.

deff fn [24]

Area of a triangle equals 1/2 base times height, or 1/2bh. So it would be 5.4 times 2, equaling 10.8. Then multiply it by 1/2, which would divide it by 2, resulting in 5.4 again. Just make sure to get your units right.
