Answer:
768 m^2
Step-by-step explanation:
<u>Separate the shapes</u>
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
<u>Calculate</u>
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2
-4x+3y=15
3y=15+4x
y=(15+4x)/3= 4/3x +5
slope: 4/3
y-intercept: 5
Answer: Range
Step-by-step explanation:
I just did it
(2x + 7) + (2x) + (x + 18) = 180
5x + 25 = 180
5x = 155
x = 31 °
Answer: -1x+3
Step-by-step explanation:
so first add the x's which is just -1x then add your whole numbers which is a positive 3 so your full answer is -1x+3
