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
Step-by-step explanation:
Hope this helps
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
