Solving for the missing term and the missing coefficient (6a − )5a = ( ) a^2 − 35a
 Let the missing term be X 
 Let the missing coefficient be Y
 Therefore, (6a – X)5a = Y(a^2) – 35a 
 6a x 5a – X.5a = Y.a^2 – 35a 
 30a^2 – X.5a = Y.a^2 – 35a 
  Equating co-efficients,
30a^2 = Y.a^2; X.5a = 35a 
 30 = Y; 5X = 35
Y = 30; X = 7 
   Therefore, (6a-7)5a = 30 a^2 – 35a

Answer:
13 white cars
Step-by-step explanation:
Let us represent:
Number of 
Red cars = x
Blue cars = y
White cars = z
Sharon has 23 toy car that are colored red, blue, and white. 
x + y + z = 23
x = 4
 2 fewer blue cars than red
y - 2 = x
 y - 2 = 4
y = 4 + 2
y = 6
Hence,
x + y + z = 23
4 + 
Number of white cars is calculated as:
23 - (6 + 4)
23 - 10
= 13 white cars
 
        
             
        
        
        
Answer:
15a^5b^15
Step-by-step explanation:
you multiply 5 and 3 to get 15, and then when you are multiplying exponents of variables, you actually add them, so a^2 times a^3 is actually a^5, and b^7 times b^8 is b^15. Because these are all multiplied together, you get the answer of 15a^5b^15.
