It’s about right triangles but it’s confusing

Answer:
Its D
Step-by-step explanation:
Imagine that we have a 2 cm straw that will be the height.
5 cm is for the base
So the upper one must longer than the base
So its 7 cm
Answer:
A
Step-by-step explanation:
Use Pythagorean Theorem, which is for side lengths of right triangles.
a^2 + b^2 = c^2 (c is the hypotenuse)
Common combination is 3-4-5. Just by looking at the answers, I can see A is 3-4-5 except everything is multiplied by 2.
B is wrong. It would be 5-12-13 if it were a RT.
C is wrong. 3-4-5
D is wrong. 4 + 25 = 49 is not an equation.

Answer:
149.71
Step-by-step explanation:
2(x - 1) > = -12
2x - 2 > = -12
2x > = -12 + 2
2x > = -10
x > = -10/2
x > = -5 or -5 < = x
wrong solution would be B. x less then or equal to -5....because x is greater then or equal to -5
Answer:
It should be C
Step-by-step explanation:
B is a quadratic function and A is a linear line.
Answer:
r o s(3)=?
s(x)= x²-1
x=3
s(3)= 3²-1
s(3)= 9-1
s(3)=8
r(8)
r(x)= -2x-1
x=8
r(8)= -16-1
r(8)= -17
r(s(3))= -17
I know this is probably too late but its 60%
