100 PTS!!!! The perimeter of a rectangle is 4(4x - 5) inches. the length of the sides of the rectangle are 2 x + 3 inches and 3x
vekshin1

Answer:

2 sides are \frac{33}{13} or 2.5

2 sides are \frac{47}{13} or 3.6

Step-by-step explanation:

There must be 2   2x+3s  and 2   3x+2s

The perimeter is the sum of the sides (it has 4 sides)

2(2x+3) + 2(3x+2) = 4(4x-5)

distributive property

2*2x + 2*3

4x+6

other one

2*3x + 2*2

6x+4

perimeter

4*4x + 4*-5

16x-20

together...

(4x+6) + (6x+4) = 16x-20

add like terms

10x+10 = 16x-20

add 20 to both sides

10x+30 = 16x

subtract 10x from both sides

30 = 26x

divide by 26 on both sides

\frac{30}{26} = x

simplify

\frac{15}{13}

Substitute the x value

2 of the sides are 2x+3

so

2(\frac{15}{13} ) + 3

\frac{30}{13} + \frac{3}{1}

\frac{33}{13}

or 2.5

other sides

3(\frac{15}{13} ) + 2

\frac{45}{13} + \frac{2}{1}

\frac{47}{13} or 3.6

That's all I can say for now! Hope this helps and a thank won't hurt! :)

lya took one hour to drive from his apartment to Philips Arena and back. The return drive took 8 minutes less than the trip to t
Phantasy [73]
An hour is 60 minutes.

The trip to the arena + The return drive = 60 mintues.

Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.

The return drive + 8 minutes = The trip to the arena

Let's represent these two equations with variables.

x + r = 60
r + 8 = x

What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.

x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26

Then use r in an earlier equation to find a.

r + 8 = x
26 + 8 = x
x = 34

Use the information given to answer the question.
Usimov [2.4K]

Comparing the functions, it is found that:

  • The function Kimora's travel based on Jim's travel is of: D. g(x) = f(x) + 80.
  • Lonnie's function based on Kimora is: B. h(x) = g(x - 2).

-----------------------------------------

Jim's equation is of:

f(x) = 140 - 55x

Kimora's equation is of:

g(x) = 220 - 55x

The -55x term is common to both functions, while the constant on g is 80 more than f, thus:

g(x) = f(x) + 80

Which means that the answer to the first question is given by option D.

Lonnie started traveling two hours before Kimora's, using the same equation of motion, just with the input x reduced by 2, thus:

h(x) = g(x - 2)

Which means that the answer to the second question is given by option B.
