I got it correct in imagine math. :)

Thank you.

Further explanations? Let me know. :)

Answer:

I would need to see the options

Step-by-step explanation:

But here is how one could look. g=3+(m/p). In this equation g is the amount of guests she can brin, m the amount of money she has and p the price to bring in guests(after the third shown be the 3+...).

Choose exactly two answers that are correct.

A.

2(4x + 7)

B.

9x – 10

C.

16x – 4

D.

4(4x – 1)

Answers

The way I would do this is to distribute the original piece and get
8 + 16x -12, which is the same as 16x -4, so C is definitely one of the answers
Next I would distribute A, which isn't an answer because 8x +14 does not equal 16x + 4. Finally I would distribute D, which comes out as 16x -4, so it is one of the answers(:
ANSWERS: C and D
I really hope this helped(:

Find the area of the lateral faces of the right triangular prism with altitude of 5 cm and base edges of length 3 cm, 4 cm, and 5 cm.

Answers

Answer:
area of lateral faces = 60 cm²

Explanation:
The lateral area of the triangular prism can be calculated as follows:
lateral area = s₁h₁ + s₂h₂ + s₃h₃

We have:
h₁ = h₂ = h₃ = height of prism = 5 cm

Therefore, the formula became:
lateral area = h (s₁ + s₂ + s₃)

We area given that:
s₁ = 3 cm
s₂ = 4 cm
s₃ = 5 cn

Substitute with these givens in the above equation to get the lateral area as follows:
lateral area = 5 (3+4+5)
lateral area = 5(12)
lateral area = 60 cm²

Hope this helps :)
