Answer:

1. x = 2

2. x = 1

3. x = 1 and 2

Step-by-step explanation:

1. 2(2) + 5 = 9 --> 4 + 5 = 9 exactly. So, yes!

2(1) + 5 = 9 --> 2 + 5 does not = 9. So, no.

2(3) + 5 = 9 --> 6 +5 does not = 9. So, no.

2. 2(1) + 5 < 9 --> 2 + 5 = 7 < 9. So, yes!

2(2) + 5 < 9 --> 4 + 5 = 9 < 9. So, no.

2(3) + 5 < 9 --> 6 + 5 = 11 < 9. So, no.

3. 4(1) - 5 < 7 --> 4 - 5 = -1 < 7. So, yes!

4(2) - 5 < 7 --> 8 - 5 = 3 < 7. So, yes!

4(3) - 5 < 7 --> 12 - 5 = 7 < 7. So, no.

Hope this helps! :)

The legs of a 45 45 90 triangle have a length of 8 units what is the length of the hypotenous
Crank

Answer:

11.31 units

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + 8^2 = c^2

64 + 64 = c^2

128 = c^2

Opposite of exponents is square roots, and we need to get rid of that exponent in c^2, meaning we find the square root.

\sqrt{128\\} \\\\ = c

c = 11.31 units
