Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 35 ( subtract 25 from both sides )
x² - 10x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 10 + 25
(x - 5)² = 35 ( take the square root of both sides )
x - 5 = ±  ( add 5 to both sides )
 ( add 5 to both sides )
x = 5 ± 
That is the second option on list
 
        
                    
             
        
        
        
P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm

Hello!  The formula for finding simple interest is prt. That means multiply the principal (initial amount) by the rate (percentage) by time (months or years). The principal is $893.78 and the interest rate is 2.2%. 893.78 * 2.2% (0.022) is 19.66316. Do not delete that number. The time is 7 years. Now multiply that number by 7 in order to get 137.64212 or $137.64 when rounded to the nearest whole hundredth.  Now, let's add both numbers. 893.78 + 137.64 is 1,031.42. There. Alfred's balance after seven years is $1,031.42.
        
             
        
        
        
Answer:
Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer. 
m=<u><em>y2-y1/x2-x1</em></u>
m=9-5/3-1
m=4/2
Simplify the answer.
m=4/2
m=2/1
Final answer is 2.
The slope is positive meaning it is ascending (going up).
