You missed to write the value of the area of circle so just for explanation purpose, I will assume that given area is 25 \pi

Now question says to find the circumference. To find circumference we first need to find the radius (r)

Hence plug the value of area into formula of the area of circle and find the radius.

Area=\pi r^2

25 \pi=\pi r^2

divide both side by pi

25 =r^2

take square root of both sides

5=r

now we can plug value or radius r=5 into formula of circumference of the circle.

circumference = 2 \pi r

circumference = 2 \pi *5

circumference = 10 \pi

Hence final answer is circumference = 10 \pi.

You can repeat same procedure with given value of area to find correct answer.

Answer:

The work shown here is correct.

It simplifies to 17x + 36y + 5.

Step-by-step explanation:

In this situation, there are four different items being purchased. This means their will be a sum of 4 terms. Each term will be the number of the item times its cost. When added together, the four terms will represent the total cost.

7 pens at $x is 7x

5 pens at $(2x+3) is 5(2x+3)

y pens at $6 is 6y

(3y-1) pens at $10 each is 10(3y-1)

All together the cost expression is 7x + 5(2x+3) + 6y + 10(3y -1).

Simplify by applying the distributive property and combine like terms.

7x + 10x + 15 + 6y + 30y - 10

17x + 36y + 5

2/3 cup of oatmeal is needed to make 10 granola bars. how many such granola bars can be made with 20 cups of oatmeal? Kindly ple
aleksandrvk [35]
2/3 cup of oatmeal - 10 granola bars

When the number of cups of oatmeal increases, the number of granola bars also increases.
If you use for example twice as many cups of oatmeal, you'll make twice as many granola bars.
Therefore, the first step is to calculate how many times 20 cups of oatmeal is more than 2/3 cup of oatmeal. To do it, divide 20 by 2/3.

20 \div \frac{2}{3} = 20 \times \frac{3}{2}=\frac{60}{2}=30

You have 30 times as many cups of oatmeal, so you'll make 30 times as many granola bars.

10 \times 30= 300

300 granola bars can be made with 20 cups of oatmeal.

please help 100 points!!! will give crown to best answer if f(x) = 3x^2 -2x + 4 and g (x) = 5x ^2 + 6x -8 find (f-g) (x)
Alexxandr [17]
(f-g)(x) will be 3x^2 -2x+4 -(5x^2+6×-8)
distribute the -sign, gives us
3x^2-2x+4-5x^2-6x+8,
now combine like terms and should get,
-2x^2-8x+12,
final answer,
(f-g)(x)= -2x^2-8x+1×,
hope it helped,
good luck
