earnstyle [38]

Answer:

24 blank shirts

Step-by-step explanation:

I'm guessing you're asking for blank shirts. 12+6+4+2=24. 24 teams so far, but there are the blank shirts.

(24+b)/2=b. Multiply by 2

=24+b=2b. Subtract b

24=b

Area of Rectangles and Squares.<br> Please show the work, I need help
USPshnik [31]

Here, I think I can help you out:

1. 21 ÷ 3

= 7

Therefore, the length is 7cm².

2. 35 ÷ 7

= 5cm²

- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.

7. All sides of a square are the same length.

7 x 7

= 49cm²

9. 2 x 3.5

= 7m²

- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)

How do you solve that?
Aleks [24]
Put it in the form 

ax^2 + bx + c = 0 

use the quadratic formula

x =  [ -b + sqrt( b^2 - 4 ac )  ] / 2a


x =  [ -b - sqrt( b^2 - 4 ac )  ] / 2a

7v^2 - 7v - 22 = 0

a = 7 
b = -7
c = -22

v = [  7 + sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7  = 2.34

v = [  7 - sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7  = -1.34

X miles per hour  -  <span> speed of the boat in still water
(x - 2)  -  speed up the river
(x + 2)  -  speed down the river
</span>
\frac{30}{x - 2} = \frac{38}{x + 2}
30 * (x + 2) = 38 * (x - 2)
30x + 60 = 38x - 76
