w represents width

4w represents length

d represents diagonal

w2 + (4w)2 = d2

w2 + 16w2 = d2

17w2 = d2

±w√17 = d

The diagonal is the width times √17.

Can someone help me please. I have to show my work.

madreJ [45]

Answer:

Step-by-step explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

A = width * lengh = 23 * 10 = 230

2. width = 7

P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

The distance from your house to the park is represented by the expression "5x + 4 more than 2 − 2x." The distance from the park

Neko [114]

Answer:

The distance from the house to the school is equal to $(4x-2)$

Step-by-step explanation:

Let

A-----> the distance from house to the park

B----> the distance from the park to the school

C----> the distance from house to the school

so

$C=A+B$

we know that

$A=(2-2x)+(5x+4)$

$B=(3x-10)-(2x-2)$

so

Find the the value of C

$C=(2-2x)+(5x+4)+(3x-10)-(2x-2)$

$C=(4x-2)$

therefore

The distance from the house to the school is equal to $(4x-2)$
