Evaluate this...
the x at the bottom cancels out one of the xs at the top so it will be
Now the one cancels out one of the 1s in the -4 so
Hope this helps :)
To find the surface area of a prism, we must find the area of each side and add them up.
Let's first find the area of the triangular base.
The area of a triangle is
Where b is the base length and h is the height.
The base length of the triangle is 10.5. The height is 10.
The triangular base has an area of 52.5 cm².
The triangular top must also have the same area. Thus, it also has an area of 52.5 cm².
Now we to find the length of the 3 rectangles on the side of the prism.
The formula for the area of a rectangle is
where
is the width and
is the length.
All rectangles have a width of 8. They all have different lengths. If we find the area of all the rectangles, we have the following:
Now, add up ALL the areas we found. We'll have our surface area once we do this.
The surface area is 385 cm². Hope this helps! :)
The Y-intercept is where the line goes through the Y-line. In this case, the Y-intercept is -3.
Slope is y2-y1/x2-x1
(5,6) (0,-3)
6-(-3)=9
5-0=5
9/5 is the slope.

first put both options into equation format. option 1: 360+75m and option 2: 24(30). solve the easier problem first which is 24 multiplied by 30 which equals 720. so now you know what should be on the side of the equal sign so that they both have eqaul solutions. 360+75m =720. subtract 360 from both sides so that equation turns to 75m=360, then divide both sides by 75 and get 4.8. it would take 4.8 months
# 1 is 20
#2 is 24
# 3 is 95
#4 is 46
