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

AnnZ [28]

Answer:

112 stamps

Step-by-step explanation:

Shaquille and Amanda's stamps are described in terms of Lyle's, so:

Lyle's = 6x                     6x+3x+2x=364

Shaquille's = 3x                       13x=364

Amanda's = 4x                            x=28

Lyle has 168 stamps, Shaquille has 84, and Amanda has 112. 168+84+112=364

puteri [66]

Answer:

15x+25 ; 70

Step-by-step explanation:

Given that,

Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.

Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :

y = 15x+25

For 3 hours,

y = 15(3)+25

= 45 + 25

= 70

So, the required option is (c) " 15x+25 ; 70 ".

Given that f(x)=2x-8, determine the average rate of change over the interval [2, 8].
8_murik_8 [283]

Answer:

2

Step-by-step explanation:

The average rate of change over [2, 8] is the change in the y-values over the change in the x-values.

\frac{f(8) - f(2)}{8 - 2}

f(8) = 2(8) - 8 = 16 - 8 = 8

f(2) = 2(2) - 8 = 4 - 8 = -4

\frac{8 - (-4)}{8-2} = \frac{8 + 4}{8-2} = \frac{12}{6} = 2
