Answer:

Area: 5x + 10

Perimeter: 2x + 14

Step-by-step explanation:

Area = length times width

Perimeter = length (2) + width (2)

<u>Area:</u>

Multiply the length be the width. That gives you 5 (x + 2).

Then use the distributive property to simplify this expression. That gives you 5x + 10.

<u>Perimeter:</u>

Multiply the width by 2. That gives you 10.

Multiply the length by 2. That gives you 2x + 4

Add the 2 together. That gives you 10 + 2x + 4.

Combine all like terms. That gives you 2x + 14.

Find the length of the function over the given interval. y = 3x from x = 0 to x = 2
olganol [36]

The length of the function y = 3x over the given interval [0, 2] is 3.2 units

For given question,

We have been given a function  y = 3x

We need to find the length of the function on the interval x = 0 to x = 2.

Let f(x) = 3x where f(x) = y

We have  f'(x) = 3,  so  [f'(x)]² = 9.  

Then the arc length is given by,

\int\limits^a_b {\sqrt{1+[f'(x)]^2} } \, dx\\\\= \int\limits^2_0 {\sqrt{1+9} }\, dx\\\\=\sqrt{10}\\\\ =3.2

This means, the arc length is 3.2 units.

Therefore, the length of the function y = 3x over the given interval [0, 2] is 3.2 units

To find X, set up a ratio with the given dimensions:

10/15 = X/42

Cross multiply:

420 = 15x

Divide both sides by 15:

x = 420 / 15

x = 28
