Answer:
195.6 inches squared
Step-by-step explanation:
First we find the value of one of the big triangles.
(14*8*0.5)
56
Next, we find the value of the three of them combined.
56+56+56 or 56*3
168
Now, we find the value of the smaller triangle.
(6.9*8*0.5)
27.6
Because we only have one small triangle, we don't need to do what we did with the other one now.
The last step is to add the area of the three triangles with the smaller triangle.
168+27.6
195.6
The surface area of the (shape...?) is going to be 195.6 in. squared.
Not sure if I’m understanding this wrong but for x you can multiply the top equation by -3 to get -12x-15y=-21 and the bottom by 4 to get 12x-8y=-48.
For y you can multiply the top equation by 2 to get 8x+10y=14 and the bottom equation by 5 to get 15x-10y=-60
Steps to solve:
4 - 3x = 2(x - 3)
~Distribute
4 - 3x = (2 * x) + (2 * -3)
~Simplify
4 - 3x = 2x - 6
~Subtract 4 to both sides
4 - 4 - 3x = 2x - 6 - 4
~Simplify
-3x = 2x - 10
~Subtract 2x to both sides
-3x - 2x = 2x - 2x - 10
~Siimplfy
-5x = -10
~Divide -5 to both sides
-5x/-5 = -10/-5
~Simplify
x = 2
Best of Luck!
