The first one is -8 then -5,6 and finally 16

X=3 (the line is on the x-axis, positive because it’s on the positive quadrant)

To solve 7-2a-5-14=-2+3a :

1) combine like terms: 7-19 - 2a = -2 + 3a, and then -10 = 5a

2) solve this equation for a: a = -10/5 = -2.

The solution of 7-2a-5-14=-2+3a is a = -2.

**Answer:**

3.22*10^8

First let us find area of triangles

area of 1st triangle is

1/2 x base x height

=> 1/2 x 1 x 5 = 5/2 cm^2

Now area of rectangle which is

Length x breadth

=> 12 x 5 = 60cm^2

Now area of 2nd triangle

=> 1/2 x 1.5 x 5

=> 15/4 cm^2

Total area = 5/2+60+15/4 = 265/4 cm^2

Or 66.25 cm^2
