The slope formula can be used to prove a triangle has
<span>a right angle
and slope formula also prove that lines are parallel
so i conclude option B is correct
hope it helps</span>
Did you mean the Pythagorean theorem? If so I believe that the answer would be that the Pythagorean theorem is used any time there is a right triangle.
The answer is 2 because you multiply them both
Answer:
The two numbers are 10 and 6.
Step-by-step explanation:
Let's begin by calling these two numbers x and y, and setting up a system of equations.
x-y=4
x*y=60
Now, you can rearrange the first equation to find the value of x expressed through y.
x=y+4
Now, you can substitute this into the second equation.
(y+4)*y=60
y^2+4y=60
y^2+4y-60=0
(y-6)(y+10)=0
y=6
x=6+4=10
Hope this helps!
The common ratio is the fifth term divided by the fourth term: -40/-8 = 5.
The seventh term is :
