Use Pythagorean theorem a^2 + b^2 = c^2
13^2 + 20^2 = c^2
169 + 400 = c^2
569 = c^2 Use square root property to get c by itself. So you find the square root of both sides
23.853 = c
Answer:
Step-by-step explanation:
4x + 3y + x + 4y
= 4x + x + 3y + 4y
= 5x + 7y
4x + 3y + 2x - y
= 4x + 2x + 3y - y
= 6x + 2y
4x + 5y - ( x + 4y )
= 4x + 5y - x - 4y
= 4x - x + 5y - 4y
= 3x + y
2x - y + 3x + y
= 2x + 3x - y + y
= 5x + 0
= 5x
You multiply then solve for y
<span>(–9.7 • 24) • (–0.25) = –9.7 • (24 • y)
</span>-232.8*(-0.25)=-232.8y
58.2=-232.8y
58.2/-232.8=-232.8y/-232.8
y= -0.25
5.8/1.2 = 58/12 = 4.83333333
rounded to the nearest hundredth
4.83
