Answer:

# Theoretically, the height of Sandy must be an odd numbers, and not less than 5.

  It may be: 7,9,11,....

# However, as 1 inch for the height of a girl is too funny - Marie can not have a height of 1 inch ( only in the case Marie and Sandy are the names of the toys!) - you should choose the number that fits best to the human height.

Step-by-step explanation:

Please see the explanation for the answer in the picture attached  below.

If Marie is 5 inches that Would make sandy 11 inches. So for every odd inch that Marie may be add 6 inches to represent Sandy”s height. I hope this somewhat helps or gives you an idea of what to do

Answer:

x = -7/2 or x =1

Step-by-step explanation:

2xx - 5x - 7 = 0

2x(x - 1) + 7(x - 1) = 0

(2x +7) (x -1) = 0

x = -7/2 or x =1

What is the area to this shape ?
Dafna1 [17]

Answer:

249.42 units²

Step-by-step explanation:

Given only the apothem of an n-sided regular polygon, the area can be computed as ...

... A = n·a²·tan(180°/n)

For n=3 and a=4√3, this is ...

... A = 3·(4√3)²·tan(60°)

... A = 3·48·√3 = 144√3 . . . . units²

... A ≈ 249.42 units²

Pls help I have no clue
suter [353]

Step-by-step explanation:

y-2 = - 3(x-3)

y - 2 =-3x +9

y -2 +2 = - 3x +9 +2

y = - 3x +11

To find the the coordinate

When x =0

y = - 3(0) +11

y= 11

When y = 0

0 = - 3x +11

Subtract 11 from both sides

-3x = - 11

x = 11/3

The y intercept is 11 so, one of your points will be at (0, 11) while the other will be at (11/3, 11).

PLEASE HELP ME! :(
snow_lady [41]
Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43

Now do the rest on your own!
