Answer:
all you have to do is multiply it through and divide it out.
Step-by-step explanation:
Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet
l=6w+4
Replace l with 6w+4
6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!
Answer:
A . because on the data set we already have the median then we use range which is max -min
Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides

2 * 60 + 2 * 130 = 380 </span>
Answer:
Step-by-step explanation:
0 -3 y intercept is -3 when x is 0
x y
-1 1 0 -3 subtract 1 for x and 3 for y
2 3
3 6
4 9
x only increase by ones y increases by threes
so the slope is y/x which means 3/1 up three, 1 to the right
y=mx+b
y = 3x-3
