To find the value of x, we will have to set the perimeters equal. 
(2x+4)*4 would be P for the square and (2x+8)*3 would be P for the triangle.
We have to set these equal and solve for x. 
(2x+4)*4=(2x+8)*3
8X+16=6x+24
-6x  -16   -6x -16
2x=8
x=4
Now we plug x=4 in for each perimeter.
Square: 2(4)+5=13
Triangle: 2(4)+8=16

How do you Graph y= x + 4
Marrrta [24]

put x=0 then y=4

put y=0 then x=-4

therefore 2 ccordintes are

(0,4) and (-4,0)

take a scale and construct a line joining these two points.

you will get the required graph.

hope it helps.

please follow if you like.

Can someone that's very good at math please help me?
gtnhenbr [62]

Answer:

35 :

t = 6.25 years

(about 6 years 3 months)

Equation:

t = (1/r)(A/P - 1)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = (1/0.04)((2500/2000) - 1) = 6.25

t = 6.25 years

The time required to get a total amount, principal plus interest, of $2,500.00 from simple interest on a principal of $2,000.00 at an interest rate of 4% per year is 6.25 years (about 6 years 3 months).

36:

The two distances are the same (out and back), so set them equal.

That is done by having a (rate)(time) equal a (rate)(time).

One time is “x” and the other is “4.8-x.”

One rate is 460 and the other is 500.

460 x = 500 (4.8 -x)

460 x = 2400 - 500x

900 x = 2400

x = 2.5 hours for the slower plane.

4.8- x = 2.3 hours for the faster plane.
