A rectangle has a length of 4 feet and a perimeter of 14 feet. What is the perimeter of a similar rectangle with a width of 9 fe
mina [271]

Answer:

Option C. 42\ ft

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its perimeter is equal to the scale factor too

step 1

Find the width of the rectangle that has a length of 4 feet and a perimeter of 14 feet

The perimeter of a rectangle is equal to

P=2(L+W)

substitute the values and solve for W

14=2(4+W)

W=7-4=3\ ft

step 2

Find the scale factor

Let

z-----> the scale factor

To find the scale factor divide the width of the larger rectangle by the width of the smaller rectangle

so

9/3=3

step 3

Find the perimeter of the larger rectangle

To find the perimeter of the larger rectangle multiply the perimeter of the smaller rectangle by the scale factor

so

3*14=42\ ft

ziro4ka [17]

The correct order to express cos3x in terms of cosx is; As shown in steps 1 to 9 below.

<h3>How to simplify Trigonometric Identities?</h3>

The steps to simplify the trigonometric identities cos 3x in terms of cos x are as follows;

Step 1; cos x = cos(2x + x)

Step 2; cos(2x) cosx - sin(2x) sinx

Step 3; 1 - 2sin^2x(cosx) -(2sinxcosx)sinx

Step 4; cosx - 2sin²x cosx - 2sin²x cosx

Step 5; cosx - 4sin²x cosx

Step 6; cosx( 1 - 4sin²x)

Step 7; cosx{1 - 4(1 - cos²x)}

Step 8; cosx{-3 + 4cos²x}

Step 9; 4cos³x - 3cosx
