X=10 because. (X-3)=-49. so (10-3) with the power of 2=-49
        
             
        
        
        
Answer:
The first term should be positive
She did not distribute the -4 properly
She added  to negative -4 instead of multiplying
 to negative -4 instead of multiplying
Step-by-step explanation:
In order to tell where she is wrong we should solve the question our selves. we are going to get the following......

So now we see that the three things she did wrong are.
The first term should be positive
She did not distribute the -4 properly
She added  to negative -4 instead of multiplying
 to negative -4 instead of multiplying
Hope this helps :)
 
        
                    
             
        
        
        
Answer:
Part 1) 
Part 2) 
Part 3) 
The answer is the option A
Step-by-step explanation:
Part 1) Find the measure of side HI
Applying the Pythagoras Theorem

substitute the values and solve for HI




Part 2) Find the measure of angle G
In the right triangle GHI

substitute the values


Part 3) Find the measure of angle I
Remember that
The sum of the interior angles of a triangle must be equal to 180 degrees
so

substitute the values


 
        
             
        
        
        
Answer:
A) 
Step-by-step explanation:
The graph has x-intercepts at  and
 and  , so our factors for the polynomial will be
, so our factors for the polynomial will be  and
 and  . This means we can rule out options B and D.
. This means we can rule out options B and D.
Our graph also has a y-intercept of  when
 when  , so if we let
, so if we let  and
 and  , we can find the multiplier:
, we can find the multiplier:

Thus, the correct equation is A) 
 
        
             
        
        
        
Answer:
x = 6 months.
The equation is given by $45 + ($49.45 × x) = ($56.95 × x).
Step-by-step explanation:
i) Let x be the number of months of Internet Service purchased till the Fast 
   Internet charges and Quick Internet charges become the same.
ii) Charges for Fast Internet for x months is given by $45 + ($49.45 × x)
iii) Charges for Quick Internet for x months is given by ($56.95 × x)
iv) According to the first statement we will now equate the equations in ii)  
    and iii) and solve for x.
    Therefore, $45 + ($49.45 × x) = ($56.95 × x)
                       45 + 49.45 x  =  56.95 x
   Therefore  (56.95 - 49.45) x = 45
                     7.50 × x  =  45
   Therefore x = 45 ÷  7.5 = 6
