Answer:
(4, ``6)
Step-by-step explanation:
The midpoint formula is
((x sub 2 - x sub 1)/2, (y sub 2 -y sub 1)/2). As shown, its written like a coordinate
Your x sub 1 is the x-coordinate of your first coordinate pair, and the rest follow the same pattern.
So, (5-(-3)/2, 8-(-4)/2)
5-(-3)=5+3=8
8-(-4)=8+4=12
(8/2, 12/2)
(4,6)
I think it is 1 I am not sure tho
Answer:
Option B
Step-by-step explanation:
Surface area of a triangular prism = Area of the triangular sides + Area of the rectangular sides
Area of the triangular sides = 2(Area of the triangular base)
= ![2[\frac{1}{2}(\text{Base})(\text{Height})]](https://tex.z-dn.net/?f=2%5B%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%28%5Ctext%7BHeight%7D%29%5D)
= 10 × 12
= 120 ft²
Area of the rectangular sides = (Perimeter of the triangular side)(Height of the prism)
= (10 + 13 + 13)(15)
= 36 × 15
= 540 ft²
Surface area of the prism = 120 + 540
= 660 square feet
Option B will be the answer.
