<h2>Answer:</h2>

<u>The dilated area will be </u><u>128 ft²</u>

<h2>Step-by-step explanation:</h2>

The original area will increase by a square of the scale factor because it is a rectangle

Since

Original Area = 8 ft²

So dilated area will be 8 x 4²

Dilated Area = 8 x 16

Dilated Area = 128  ft²

How do the graphs f(x)= |x| and g(x)= 3 3|x| relate
Studentka2010 [4]

Answer:

Option a. The graph of g(x) is the graph of f(x) stretched vertically.

Step-by-step explanation:

If we draw a graph of f(x) = |x| and g(x) = 3|x| and we compare them

we find that g(x) is stretched vertically.

Now we will check it from both the graphs.

For graph y = |x|

for x = 4

y = 4

But for second graph which is y = 3|x|

for x value = 4

y = 12

Therefore for y values graph g(x) got stretched vertically.

Hence option a. is correct.

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month. Her friend Kate’s hair is 16 inches long and grows
Gelneren [198K]
<h3>18 months will pass before the two friends have the same hair length</h3>

<em><u>Solution:</u></em>

Let "x" be the number of months

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month

Equation : 13 + \frac{2}{3}x ------- eqn\ 1

Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month

Equation: 16 + \frac{1}{2}x ----- eqn\ 2

<em><u>For two friends to have the same hair length, eqn 1 must be equal to eqn 2</u></em>

13 + \frac{2x}{3} = 16 + \frac{x}{2}\\\\\frac{2x}{3} - \frac{x}{2} = 16 - 13\\\\\frac{4x}{6} - \frac{3x}{6} = 3\\\\x = 18

Thus 18 months will pass before the two friends have the same hair length

Hello There!

First work out the number of shelves per bookcase:
65/13 = 5
It is 5 shelves per bookcase.
6 x 5 = 30.
Therefore 32 shelves are enough to make 6 bookcases.

Hope This Helps You!
Good Luck :)
