a. factor A = x^2 -30x + 225 = (x - 15)(x - 15)
side length =<u> (x - 15)</u>
b. add (x - 15) four times = 4(x - 15) =<u> 4x - 60</u>
Answer:
$32
Step-by-step explanation:
The lady charges $2.00 for gas which means over a 4 hour period we would do
4 x 2 = 8
She makes a total of 8 dollars

24
We add these values to get $32
Answer:
10
Step-by-step explanation:
The current probability of picking a red ball is . When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).
60 = 4x + 20
40 = 4x
x = 10 red balls
Because 21 is more than 1
