The perimeter of a triangle is 42 yards. the first side is 5 yards less than the second side, and the third side is 2 yards less than the first side. what is the length of each side?

First side = 13 yarsd

Second side = 18 yards

third side = 11 yards

Step-by-step explanation:

Let the second side of the triangle be x.

Then the first side must be

and the third side must be

We know that the perimeter of triangle = Sum of all sides .

Therefore, we have

Hence, the length of second side = 18 yards

The length of first side = 18-5=13 yards

The length of third side = 13-2=11 yards

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
