What is an equation of the line that passes through the point (3,6) and is parallel to the line 2x+3y=21

y = -2/3x + 8

Step-by-step explanation:

first convert equation into y = mx + b form

3y = 21 - 2x

y = 7 - 2/3x

slope is -2/3

y -6 = -2/3 (x -3)

y - 6 = -2/3x + 2

y = -2/3x + 8

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
