(x+10(2x+5)) to find the area of the full shape
2x^2+5x+20x+50
2x^2+25x+50 (simplified), then subtract the area of the square inside which is
(x+1)(x+1) = x^2+x+x+1 = x^2+2x+1
(2x^2+25x+50)-(x^2+2x+1)
x^2+23x+49 is the final answer

Do you remember how to find the equation of a line when you know two points on the line ? Well, that little table gives you FIVE points on the line, and in case some students didn't notice that, the table even labels the columns 'x' and 'y' as a hint. With 5 points given, there are 20 different ways to find the equation of the line. Get to work.

At a small private college 9 / 20 of the students are female if there are 2160 female students how many male students
drek231 [11]

Answer:

4800

Step-by-step explanation:

x is the number of total students

x * 9/20 = number of female students

x * 9/20 = 2160

Multiply each side by 20/9

x * 9/20 * 20/9 = 2160 * 20/9

x =4800

Explain why multiplying two irrational numbers could result in either an irrational number or a rational number.
Nimfa-mama [501]
Because if you multiply 2 different irrational numbers (like the following)
\sqrt{3} \times  \sqrt{17}
You will get an irrational answer.

BUT
if you multiply the same square root (which are both irrational, you get a rational number)

\sqrt{3}  \times  \sqrt{3}  = 3

Sierra is saving money to buy a bike the bike costs $245. she has $125 saved and each week she adds $15 to her savings. how many
beks73 [17]
You should start with an equation.
245 = 125 + 15x
The 'x' represents the week.

so now, we have to subtract 125 from the total amount which is 245.
245 - 125 = 120
now we have
120 = 15x
to find 'x', we must divide 15 on each side
\frac{120}{15}  =  \frac{15x}{15}
we are now left with
8 = x
that means Sierra will have 8 weeks until she has enough money to buy the bike
