Step-by-step explanation:
3 of the 4 options aren't prisms
A is a cuboid
B is a cube
C is a prism
D is a pyramid
Answer:
13) x=n-11
15) x=3*10
Step-by-step explanation:
I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be right if a² + b² = c²
A.
a² + b² = 12² + 13² = 144 + 169 = 313
c² = 25² = 625
313 ≠ 625
B.
a² + b² = 36² + 77² = 1296 + 5929 = 7225
c² = 85² = 7225
7225 = 7225 ← right triangle
C.
45, 45, 45 ← this is an equilateral triangle (all angles = 60°)

D.
</span>a² + b² = 45² + 56² = 2025 + 3136 = 5161
c² = 67² = 4489
5161 ≠ 4489
Answer is B
(4^3)^5
= 4^(3*5)
= 4^15
Its D
Please note that this is not an equation ( no = sign), Its best described as an exponential expression.
Answer:
- y = 6/7 x - 6 Your answer could be
- y = 0.857 x - 6
Step-by-step explanation:
Remark
- Start by solving for y. Divide both sides by 7
- y = 6/7 x - 14/7
- y = 6/7 x - 2
- Parallel lines all have the same slope. What you know so far is that the slope of the new line must be 6/7
- y = 6/7x + b
- Now you use the given point to solve for b
Givens
Solution
- 0 = 6/7 * 7 + b Reduce the fraction
- 0 = 6 + b Subtract 6 from both sides
- -6 = 6 -6 + b
- b = - 6
Answer
- y = 6/7 x - 6 Your answer could be
- y = 0.857 x - 6
