The length of a rectangle is 4 more than it's width. Write an equation that will determine the dimensions if the area of the rec

Firdavs [7]

Answer: The equation is W^2 + 4W - 96= 0

{Please note that ^2 means raised to the power of 2}

Step-by-step explanation: We have been given hints as to the measurement of the length and width of the rectangle. The length is given as four more than the width. What that means is that whatever is the width, we simply add four to get the measurement of the length. Therefore if the width is W, then the length is W + 4.

That is,

L = W + 4 and

W = W

Also we have the area given as 96.

Remember that the area of a rectangle is given as

Area = L x W.

In this question, the Area is expressed as

Area = (W + 4) x W

96 = W^2 + 4W

Subtract 96 from both sides of the equation and we have

W^2 + 4W - 96 = 0.

We now have a quadratic equation from which we can determine the dimensions of the rectangle

Answer:

the arc length is 555.17 cm

Step-by-step explanation:

The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·

You want to find the distance the golf club travels when the golfer swings the club.

First you need to subtract 25° from 360°

360° - 25° = 335°

now you need to convert 335° into radians

radians = degrees ·

radians = 335° · you multiply 335° by

radians = 335/180 then you simplify

radians = 67/36

335° = 67 $\pi$ /36

Now we plug everything we know into the equation s = rΘ

s = rΘ

s = 95 (67 $\pi$ /36) first multiply 67 by 3.14

s = 95 (210.38/36) divide 210.38 by 36

s = 95 (5.843888889) and multiply 95 by 5.843888889

s = 555.1694444 *remember to simplify to the nearest hundredth

s = 555.17 cm

hope this helps! if u have any questions, let me know!

xxTIMURxx [149]

Answer:

the amount of soil needed is $90 in ^3$

Step-by-step explanation:

N/B: the width is 8 in

this problem bothers on the mensuration of solid shapes, rectangular prism

Given data

length l= 15 in

width w= 8 in

height h= 3/4 in

The amount of soil need in the flower box is equivalent to the volume of the box for the given data.

$volume- of- soil= L*W*H\\\volume- of- soil= 15*8*(3/4)\\\volume- of- soil= \frac{360}{4} \\\volume- of- soil=90 in^3$
