Step-by-step explanation:

2(x-3)=y+1

distribute the 2 through the parentheses

2x-6=y+1

2x+6=0+1

(change the y to 0)

2x-6=1

add 6 to both sides(+6 cancels out -6)

2x=1+6

divide both sides by 2

x=7/2 or x=3.5

hope this helps!

Area of the rectangle

$= l \times b$

$= 8 \times 6$

$= 48 {in}^{2}$

Area of the semicircles

$= 2 \times ( \frac{1}{2} \pi {r}^{2} )$

$= \pi {r}^{2}$

$= \pi {3}^{2}$

$= 9\pi$

$= 9 \times 3.14$

$= 28.26 {in}^{2}$

Area of the figure

$= 48 + 28.26$

$= 76.26 {in}^{2}$

= 76.3in²

A stadium has 48,000 seats. Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C. The number of seats in

Ira Lisetskai [31]

I had a super-ugly equation that didn’t work, but it got me close. (24,000/12,000/12,000 or so)
Then I adjusted the numbers to make the money work.

I’m sorry I can’t help more.

24,000(25) + 14,200(20) + 9,800(15)
= 600,000 + 284,000 + 147,000 = 1,031,000

Section A = 24,000 seats
Section B = 14,200 seats
Section C = 9,800 seats

14,200 + 9,800 = 24,000 seats

Step-by-step explanation:

Derivative of:

f(x) = Sin^2(cos(x^2))

f'(x) = cos^2(-sin(x^2)

f'(x) = - cos^2(sin(x^2))
