Answer:

A. 5

Step-by-step explanation:

use pythagorean theorem: a^2 + b^2 = c^2

but since we are finding the value of A; we'll use a= (square root) c^2 - b^2

A= 13^2- 12^2

A= 169 - 144

A= 25

A= 5 ( because we square root 25)

Simplify (2x + 3)(x – 4) = ?
Lina20 [59]
Use the FOIL method (first, outside, inside, last) to multiply:

2x^2-8x+3x-12

This can be simplified even more into:

2x^2-5x-12.

Hope this helped!

A hockey puck strikes a wall at an angle of 30 degrees. the puck then travels away from the wall at the same angle.
patriot [66]

Two or more angles whose sum is 180° are called supplementary angles. The measure of the ∠y is 120°.

<h3>What are supplementary angles?</h3>

Two or more angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Given the puck strikes the wall at an angle of 30°, it goes away at the same angle of 30°. Therefore, the measure of angle y can be found using the sum of the angle as a supplementary angle. Thus, we can write,

30° + ∠y + 30° = 180°

60° + ∠y = 180°

∠y = 180° - 60° = 120°

Hence, the measure of the ∠y is 120°.

10+25+15=50

25/50

I can be simplified.

The greatest common factor is 25.

25/25=1

50/25=2

So the answer is 1/2.
