From the Pythagorean Theorem, we know that a^2+b^2=c^2
28^2+21^2=(5x)^2
784+441=25x^2
1225=25x^2
49=x^2
x=7
The length of the hypotenuse would be 35m.
125 = 6 dimes = 60 and 13 nickles = 65
60+65= 125
Hope i was the brainliest asnwer.
slope = (y2-y1)/(x2-x1)
the first slope is 0 (horizontal line)
second slope is undefined (vertical line)
Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
