A regular hexagon (6-sided figure) has sides that are all the same length. Each side length is represented by the expression x + ⅓ y. a) Write an algebraic expression that represents the perimeter of the hexagon. b) Use one of the expressions and evaluate the perimeter of the hexagon if x = 5 and y = 6 HELPPPPP!!!!!

Answers

Answer 1

Answer: perimiter=6 times legnth of one side
P=6(x+1/3y)
P=6x+6/3y
P=6x+2y

if x=5 and y=6
P=6(5)+2(6)
P=30+12
P=42

A. P=6x+2y
B. 42 units is the perimiter

Which of the ordered pairs in the form (xy) is a solution of thisequation?

6x - y/2 =14

(-9, 3), (2, - 4)

A. Neither is a solution

в. The first is not a solution, but the second is

C. Both are solutions

D The first is a solution but the second is not

Answers

Plug in the 2 values for x and y into the equation and see if it works out.
6(-9)-(3)/2=14 => -54-3/2=14 => -55 -1/2 = 14
Which false so the first point is not a solution.
Next point:
6(2)-(-4)/2=14 => 12+2=14 => 14=14
This is clearly true, so the second point is a solution.

Final answer:
Answer choice B, the first is not a solution but the second is.
Hope I helped :)

so an easy way is to make it into slope intercept form y=mx+b (not nessecary by helps)

6x-y/2=14
6x=14+y/2
6x-14=y/2
y/2=6x-14
y=12x-28

just plug in the values and
(-9,3)
3=12(-9)-28
3=-108-28
obviously wrong

(2,-4)
-4=12(2)-28
-4=24-28
-4=-4
seconone is correct so then answer is B (the first is not a solution, but the second is)

A rectangular prism has a volume of 34.224 cubic meters. The height of th box is 3.1meters, and the length is 2.4 meters. What is the width

Answers

v = l × w × h
34.224 = 3.1 × 2.4 × w
34.224 ÷ 3.1 ÷ 2.4 = w
4.6 = w

The width for this rectangular prism is 4.6 meters.

i am pretty sure that the correct answer will come out to be 4.6 meters

C: z ( 10 / 5 )
D: 5 ( z - 10 )

Answers

Answer: B

Step-by-step explanation:

First off, choices A and D can be elimination because you are not subtracting. In choice C, we have 10 divided by 5 as opposed to z divided by 5. The answer is B.

You want to put $2,500 in a simple interest account. It has a 4% annual interest rate. How long will it take you to earn $200 in interest?

Answers

I=PRT
I=interst
P=present amount
R=interest rate
T=time in years

we know that
P=2500
R=4%=0.04

we also know that we want 200 in interst or I=200
we need to knw T

so
200=2500(0.04)(T)
200=100(t)
divide both sides by 100
2=T
2 years
