Answer:

Step-by-step explanation:

The area of a sector in terms of radians as opposed to degrees is

A=\frac{\theta}{2\pi }*\pi r^2

Filling in the formula accordingly gives us

A=\frac{1.75rad}{2\pi rad}*\pi (2)^2

The radians cancel out, the pi's cancel out, the 2 in the denominator cancels out (divides into 2-squared once), leaving us with

A = 1.75(2) so

A = 3.5 units squared

Factor the expression<br> 20g3 + 24g2 – 15g – 18
abruzzese [7]
First, put parenthesis around the first two numbers and the last two numbers. 
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis. 
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis. 
(5g+6) (4g²-3) 
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.

tigry1 [53]

Hello from MrBillDoesMath!

Answer:

5, 10, 0

Discussion:

Let "f" be the first number. Then the questions tells us that

f + 2f  + (f-5) = 15           =>

f + 2f + f - 5 = 15            => add 5 to both sides

4f = 5+ 15 = 20              => divide both sides by 4

f = 20/4 = 5

The numbers as

f:        5

2f:     10

(f-5):  0

Thank you,

MrB
