Answer:
minus 4
Step-by-step explanation:
y=3x-7
y=3-7
y=-4
(1,-4)
P = 2L + 2W, keep that in mind (W=width, L=length)
Just fill it in. 82=2(5+2w) + 2w. First solve for w.
82 = 10+ 10w + 2w,
82 = 10 + 12w. Now subtract the 10 from both sides, and get:
72 = 12w, now divide both sides by 12, and get:
6 = w.
W is 6.
Now to solve for L, go back to the problem we had, L = 5 + 2w. Fill in w,
L = 5 + 2(6), and then it is L = 5 + 12.
It is a simple addition equation now.
L = 17, W = 6
Answer:
228
Step-by-step explanation:
[Formulas Below]
Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is <u><em>228</em></u>.
<u><em>Area of Triangle = (Length * Height)/2</em></u>
<u><em /></u>
<u><em>Area of Rectangle = Length * Width</em></u>
Order of Operations:
46 • 4= 184
Then 184-8= 176
So your answer is 176
