Andrew drew a square with each side measuring 3 inches. Lindsay drew a triangle with each side measuring 4 inches. Which shape has a greater perimeter? Write an equation to help explain your answer. Select the correct answer below, and fill in the answer boxes to complete your choice.
(Use the operation symbols in the math palette as needed.)
A.
The square has a greater perimeter of
nothing inches. An equation for the perimeter of the shapes is
nothing.
B.
The triangle has a greater perimeter of
nothing inches. An equation for the perimeter of the shapes is
nothing.
C.
Both shapes have a perimeter of
nothing inches. An equation for the perimeter of the shapes is
nothing.

C.

Both shapes have a perimeter of

12 inches. An equation for the perimeter of the shapes is 3 + 3 + 3 + 3 = 4 + 4 + 4.

Step-by-step explanation:

Since a square has 4 sides, we need to multiply 3 by 4 which is 12. Since a triangle has 3 sides, we need to multiply 4 by 3 which is 12. Therefore, both shapes share the same perimeter.

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
