Answer:
516 cm squared
Step-by-step explanation:
To find the surface area of a rectangular prism such as this, is basically just like finding the OUTSIDE surfaces. We are looking for the "perimeter" of a 3D shape.
How do we do it?
- Calculate each face of the prism by multiplying Length x Width.
- Make a shortcut by combining like-figures (front of the cube and back of the cube are the same surface areas, etc.)
- Make your formula
- 2(4 · 15) + 2(10 · 15) + 2(12 · 4)
H is equal to 8
M is equal to 15.3
20-12= 8
9+6.3= 15.3

Answer:
Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to
we have
(-3,1) and (0,3)
substitute
step 2
Find the equation of the dashed line in slope intercept form
we have
---> given problem
substitute
step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so
see the attached figure to better understand the problem
It is misleading because the points on the x-axis are not in the same unit. The years should be numbered the same units.(:
