1. A) A highway noise barrier is 120 m long is constructed in 2 pieces. One piece is 45 m longer than the other one. Find
the length of each piece. B) If you are to construct a
rectangle with each of the sizes of the pieces being the
length and width then what is the perimeter? c) What would be
the area of that rectangle? (Note: Use an Equation to shlyel

123m lojng is thje ocean.

Step-by-step explanation:

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
