Jenny's algebraic expression: 
y = 33d 
where y is the total number of posts 
total tweets in 5 days 
y = (33)(5)
y = 165 tweets 
Antonio's expression: 
y = 5d 
total tweets in 5 days 
y = (5)(5) 
y = 25 tweets 
Altogether they have posted: 
165 + 25 tweets = 190 tweets in five days 
        
             
        
        
        
The root is the x intercepts or the zeros of the problem
If I were to graph
(x-5)(x+4)=0
We need a number for x which makes this equation 0
The numbers are 5 or -4 
These are the x intercepts of the parabola or roots
 
        
                    
             
        
        
        
The length of the windshield wiper to the nearest inch is 24 inches
<h3>How to calculate the area of a sector</h3>
The formula for calculating the area of a sector is given as:
A = r²β/2
r is the length of the wiper
β is the subtended angle
Given the following
A = 500.3 square in
β = 98 degrees = 98pi/180 = 49pi/90
Substitute
500.3 =  r²49pi/180
500.3 = 153.86r²/180
153.86r² = 90054
r² = 585.298
r = 24.19
Hence the length of the windshield wiper to the nearest inch is 24 inches

To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.



Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.
