width = x

length = 2x+8

area = l x w

x<span>(2x+8)</span>=120

<span><span>2<span>x^2</span>+8x−120=0 </span> </span>

<span><span><span>x^2</span>+4−60=0 </span></span>

<span><span><span>(x+10)</span><span>(x−6)</span>=0</span> </span>

<span><span>x=−10 and x=6 </span></span>

<span><span> width has to be a positive number</span></span>

Width = <span>6 </span> inches.

What is the inverse function of y = √ x − 1 2 , x ≥ 1 2a. y=x2−14,x≥0 b. y=x2−12,x≥0 c. y=x2+12,x≥0 d. y=x2+14,x≥0
hammer [34]

The function is :

y = √(x-12), x≥12


To find the inverse function, we interchange x and y, and then make y the subject again.


So interchanging x and y we have:


x = √(y-12)


Squaring both sides gives;

x² = y-12



Now making y the subject we have,


y = x² +12

x≥0.


Therefore the inverse function is;

y = x² +12, x≥0.


Hence the correct answer is C.

Trucks are delivering gravel to a construction site each truck hold 7.5 cubic yards of gravel. The weight of 1 cubic yard of gra
Romashka-Z-Leto [24]
The first thing you must do is to calculate the weight of the gravel (w) that the truck holds (7.5 yards³). So, you have:

 If the weight of 1 yard³ is 1.48 tons, then the weight of 7.5 yards³ is:

 w=7.5x1.48 tons
 w=11.1 tons

 The problem says that the gravel will be placed in containers that each hold 3.7 tons of gravel,so, If they need 1 cotainer to place 3.7 tons, how many containers they need to place 11.1 tons?

 1 container-------3.7 tons of gravel
                 x-------11.1 tons of gravel

 x=(11.1x1)/3.7
 x=11.1/3.7
 x=3 containers

 H<span>ow many containers of this size are needed to hold all the gravel from one truck?
</span>
 The answer is: 3 containers.

1/4 pound of green grapes and 2/3 pound of red grapes She ate 1/2 pound of the grapes . What is the amount of grapes Natasha has
JulijaS [17]

Answer:

5/12 left

Step-by-step explanation:

1- you need to take 1/4 and 2/3 and find a common denominator, to find the exact amount of pounds.

2- Once you have 3/12 and 8/12, add them to get 11/12.

3-Now you know you don't have a full pound. Then subtract 1/2 from 11/12 ->

11/12 - 6/12 = 5/12
