How to solve 5x+6=-4

IceJOKER [234]

Solve for x.
Minus 6 from both sides. I will look like this: 5x+6-6=-4-6. It now equals 5x=-10. Divide both sides by by 5. Now, x=-2

Please help!! What is the area of the trapezoid? I will mark brainliest! (If it is correct)

boyakko [2]

Answer:

30 $in^{2}$

Step-by-step explanation:

First find the area of each individual shape.

3 x 4 = 12 / 2 = 6 for the triangle on the left

5 x 4 = 20 for the rectangle

2 x 4 = 8 / 2 = 4 for the right triangle

Now all yo udo is add them all up to get the total area

6 + 20 + 4 = 30 $in^{2}$
