Answer:
a = 20 and b = 21
Step-by-step explanation:
Given:
2a-3b = -23
a and b are consecutive
Find:
a and b
Computation:
a = b - 1
So,
2a-3b = -23
2(b-1)-3b = -23
2b - 2 - 3b = -23
-b = -21
b = 21
So
a = b - 1
a = 21-1
a = 20
To find the surface are, we can add up the area of all of the sides.
Top:
4in x 9in = 36in^2
Bottom:
<span>4in x 9in = 36in^2
</span>
Front:
5in x 9 in = 45in^2
Back:
<span>5in x 9 in = 45in^2
</span>
Right:
4in x 5in = 20in^2
Left:
<span>4in x 5in = 20in^2
</span>
Adding them all together:
36+36+45+45+20+20 = 202in^2
The surface area of the prism is 1. 202 in^2
