Answer:
Length: 7
Width: 4
Step-by-step explanation:
We can create a system of equations for this problem, where 
is the width and 
is the length.
The perimeter of a rectangle is twice its length added to twice its width.
The length is 3 more than the width:
We can now substitute in 
as in the equation .
Distribute the first terms:
Combine like terms:
Subtract 6 from both sides:
Divide both sides by 4:
Now we know that w = 4. We can now substitute this inside an equation to find .
Hope this helped!
Answer:
1`. y = 4x+6
2. y = -6x + 29
3. y= 3x+1
4. y = x -2
5. y = 11.5x+ 3
6. y = -2x -4
Step-by-step explanation:
Answer:
Step-by-step explanation:
a) the points (0,60) and (6.0) are the intercept points for the graph of the car slowing down ( accelerating in the opposite direction than it's traveling)
we already know the slope of the line b/c that the rate at which it's slowing .. -10 =m which is the slope of the line .. down 10
use the point-slope formula y-y1 = m(x-x1) and plug in either given point for (x1,y1)
b) y -60 = -10(x-0)
y= -10x+60
thats the slope-intercept form of the equation
SA=2pir^2+2hpir=2pir(r+h)
h=2r=2(2x+3)=4x+6
SA=2pi(2x+3)(2x+3+4x+6)
SA=(4x+6)(pi)(6x+9)
SA=24πx²+27πx+54π
932 in the green box and 9 in the gray box
