Scalene right triangle-
None of the angles are congruent so it’s scalene, but since a it has a 90 degree angle it is also a right triangle
Answer: See below
Step-by-step explanation:
1. For this problem, you see that it's 5². The only problem that displays 5² is A². Now, there is a ×3 after that. That means there is 3 of 5². If you are still not sure, you can solve the problem.
5²×3=25×3=75
A shows 75.

2. You need to first distribute each factor and then combine like terms.
-14a+10b+20a-32b+2
6a-22b+2
B

3. You need to first distribute each factor and then combine like terms.
-6n+30+18n-12
12n+18
D
It's already in simplest form, 13 is a prime number
The area = π r² = π * 18² = 324 π in²
The first choice is the correct
Answer:
Step-by-step explanation:
9 - 4x > = 5 or 4(-1 + x) - 6 > = 2
-4x > = 5 - 9 -4 + 4x - 6 > = 2
-4x > = -4 4x - 10 > = 2
x < = -4/-4 4x > = 2 + 10
x < = 1 4x > = 12
x > = 12/4
x > = 3
answer is : B
