I need help with these.
sattari [20]

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

6.

26/13 = x/12

2 = x/12

x = 24

Can you help me ? Look at the question
stira [4]

Answer:

The answer is c

Step-by-step explanation:

This is because you subtract 6 to get 9 ≤ -3x then when you divide to get x by itself, then the sign has to flip so you end up with -3≥x. And when you put it on a numbers line the arrow or way it goes is the way the arrow is pointing, so if the sign is like this > it would go to the right on the number line and the converse is true as well please give me brainliest.
