Answer:
12x+20
Step-by-step explanation:
Perimeter of a garden = 4s, s being the length of the side
In this case, s = 3x+5
substitute the equation
4(3x+5)
=12x+20
Answer:
A. y = 3x + 3
Step-by-step explanation:
Slope = change in y / change in x
From 3 to 5 (x) = +2
From 12 to 18 (y) = +6
slope, m = 6/2 = 3
Using point slope form
y - y1 = m (x - x1)
y - 12 = 3 (x - 3)
y - 12 = 3x - 9
y = 3x -9 + 12
y = 3x + 3
Surface area= sum of all the areas of the shapes that cover an object
area of a one face= 4
number of faces= 37
surface area= 4×37=148
