A rectangle has a perimeter of 64 the with is 3 less than the length the equation for the scenario is 2x+2(x-3)=64

what does the variable x represent in the equation

length

Step-by-step explanation:

what will finding x-3 determine

width

for edgen its length for the first one and width for the second one

Step-by-step explanation:

because i took one for the team ;)

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

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)
