Answer:
D. 6 + 6 + 30 + 40 + 50 = 132
Surface area of triangular prism:
(perimeter of base) × length + base × height
(s₁ + s₂ + s₃)(l) + bh
Here, provided with:
- s₁ = 3
s₂ = 4
s₃ = 5
- l = 10
- b = 4
- h = 3
So, the surface area:
Only option D gives 132 as an answer which is equivalent to the area.
Answer:
D. (x - 8) (x - 8)
Step-by-step explanation:
-16x must be split into two terms that can be added to get -16, and multiplied to get 64. The only two terms that can satisfy this, is -8.
(x - 8) (x - 8)
If you're unsure about whether it's correct, you can multiply the two together to see if you get your original expression, , as your answer.
