Step-by-step explanation:

multiply the 9 in the first parentheses by x and 9 in the other parentheses and add all together
(x+9)(x+9)
x² + 9x + 9x + 81
x² + 18x +81
multiply the x in the first parentheses by x and -7 in the other parentheses and multiply the -7 in the first parentheses by x and -7 in the other parentheses and add all together
(x-7)(x-7)
x² -7x - 7x +49
x² - 14x +49
(2x-1)² is the same as (2x-1)(2x-1)
multiply the 2x in the first parentheses by 2x and -1 in the other parentheses and multiply the -1 in the first parentheses by 2x and -1 in the other parentheses and add all together
(2x-1)(2x-1)

(I forgot to place the picture) A local taxi company charges a base fare of $3.20. The taxi company charges $0.40 for every minute the taxi is in service.
Answers
Answer:
5 minutes costs 5.20 10 minutes cost 7.20 $20 gets you 42 minutes
Step-by-step explanation:
for 5 and 10 multiply the number of minutes by the price per minute then add 3.2 base fee. 5*.4=2 +3.2=5.2 10*.4=4 +3.2=7.2
For $20 subtract the 3.2 base fee (16.8) and divide that by the .4 a minute fee to get 42 which would be 42 minutes.
In 1998 there were 305 students who graduated from high school. In 2019, there were 356 students. What is the rate of change in the number of students?
1. About 1 student per year
2. about 51 students per year
3. about 2 students per year
4. about 5 students per year
Answers
Answer:
3. about 2 students per year
Step-by-step explanation:
The rate of change would be the difference in the number of students divided by the number of years passed.
So, rate of change = [tex]\frac{356-305}{2019-1998}[/tex]
= [tex]\frac{51}{21} = 2.43[/tex]
So it's around 2 students per year.

A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon’s vertical position is 12 meters and the canoe’s is -4.8 meters. The equation represents this situation.
Answers
Complete question :
A balloon is floating above a lake and a sunken canoe is below the surface of the lake the balloons vertical position is 12 meters and the canoes is -4.8 meters the equation the equation 12+d= -4.8 represents the situation 1. What does the Variable d represent 2. What value of d make the equation true
Answer:
d = lake
d = - 16.8
Step-by-step explanation:
The scenario described is represented by the equation :
12 + d = - 4.8
The variable d in the equation would refer to the surface of the lake. Hence, the lake is represented as d ;
For the equation above to be true such that the position of canoe is - 4.8
The we solve for d in the equation given :
12 + d = - 4.8
12 + d - 12 = - 4.8 - 12
d = - 16.8
