Answer:
638.32 yd²
Step-by-step explanation:
The surface area of any figure can be found by calculating the area of all the sides and finding the sum. In a rectangular pyramid, there is a rectangular base (l x w) and the same two triangles on one side and another two identical triangles on the other side.
Area of rectangle: A = l x w
Area of a triangle: A = 1/2(b)(h)
Rectangle: 16 x 13.4 = 214.4 yd²
Bottom/top triangles: 14.1 x 16 = 225.6 yd²
Side triangles: 14.8 x 13.4 = 198.32 yd²
Total: 198.32 + 225.6 + 214.4 = 638.32 yd²

Hello!
Here's how to solve for x.
27=17+2x
Our first step is to subtract 17 from both sides, leaving us with
27-17=17(-17)+2x --- > 10=2x
We then divide both sides by 2 to isolate x!
10/2=2x/2
10 divided by 2 gives us 5 meaning that x=5
3x60 is 180 and 2x70 is 140 add is 320
Answer:
-6
Step-by-step explanation:
Combine or subtract like term.
-8-3k-3k+2
-8+2-3k-3k=-6(-3k-3k)=-6(1)
