Answer:

The answer to your question is below

Step-by-step explanation:

Inequality 1

                        7(x + 2) - 8 ≥ 13

                        7x + 14 - 8 ≥ 13

                        7x + 6 ≥ 13

                         7x ≥ 13 - 6

                         7x ≥ 7

                           x ≥ 7/7

                           x ≥ 1

Inequality 2

                       8x - 3 < 4x - 3

                        8x - 4x < - 3 + 3

                               4x < 0

                                 x < 0 / 4

                                 x < 0

Interval notation   (-∞ , 0) U [1, ∞)

Is this a right triangle why or why not?
Marysya12 [62]

Answer:

No, it does satisfy the Pythagorean Theorem  

Step-by-step explanation:

In right triangle a² + b² = c²

Where a and b = legs and c = hypotenuse

The given measures of the legs are 3 and 7 and the given measure of the hypotenuse is √57

Which means that if this is a right triangle then 3² + 7² = √57²

3² = 9

7² = 49

√57² = 57

9 + 49 = 58

we're left with 57 ≠ 58 which is not true, meaning that , that is not a right triangle
