Answer:
Step-by-step explanation:
The length of a rectangle is three times the width. Find the width if the perimeter is 80 cm.
PERIMETER = 2L +2W
L=3W
PERIMETER= 2(3W) +2W
80= 6W +2W =8W
80=8W
W=10
L=3X10=30

(2x10) + (2X30) =20+60=80
x
Super easy just add 2 in front of Na H CO3(s). Your formula will be balanced.
Answer:
The linear equation is the equation of straight line. where m is the slope of the line and c is the y-intercept. Thus, the y-intercept is expressed as (0, c). That is where the graph intercepts the y-axis (thus, the x value would be 0).
