Answer:
x² + 18x +81
x² - 14x +49
4x²- 4x - 1
Step-by-step explanation:
multiply the x in the first parentheses by x and 9 in the other parentheses and
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)
4x²-2x-2x+1
4x²- 4x - 1

solve the following equation for the value of b. SHOW UR WORK!
16 + 5b = 7b + 4
Answer:
16=2b+4
12=2b
b=6
.............
Answer:
b = 6
Step-by-step explanation:
16 + 5b = 7b + 4 <-- Subtract 5b from the left
16 = 2b + 4 <-- Subtract 4 from the right
12 = 2b <-- Divide by 2
b = 6
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.
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

#CMIIWfind radian measure when r=2.5m and l=4.5cm
Answer:
Step-by-step explanation:
s = rθ, where r is the radius, θ is the radian measure of the central angle, and s is the arc length.
4.5 = 2.5θ
4.5 / 2.5 = θ
1.8 = θ

Answer:
what the question?
Step-by-step explanation:
It is also called as the constant of proportionality. It is also called as the constant of proportionality. *
Answer:
constant of variation
Step-by-step explanation:
Constant of variation and constant of proportionality mean the same and they are used in variations.
For instance:
[tex]y = 2x[/tex]
In the above equation, y varies directly as x and the constant of proportionality or variation is 2.
It is often represented with k (though, other alphabets can also be used)

Step-by-step explanation:
A construction company wants to hire x carpenters for $220 a day and y plumbers for $260 a day. the company wants to hire at least 18 workers. it wants to pay no more than $4500 each day.
write a system of inequalities to model the situation (use >, <, <=, =>)
Answer:6
Step-by-step explanation:
$220 × 6 = $1320 this is how much it cost to pay 6 carpenters for one day. Now lets find how much it cost to 12 plumbers at $260 a day. $260 × 12 = $3120 this is how much it costs to pay 12 plumbers a day.

(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.
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.
