Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3). 

To make this expression a perfect square,
a² = 
= 
Therefore, the missing number will be
.

Answer:
He can repair 9 books in 6 weeks
Step-by-step explanation:
1.5 x 6 = 9
A is for Alexis and F is for Francisco
A = 1/6 + 1/2 + 1/2 = 1 and 1/6
F = 2/3 + 1/2 + 1/3 = 1 and 1/2
1 1/6 < 1 1/2
A < F
Francisco ate the most pie.
1/6 of cherry pie is left.
No apple pie is left.
1/6 blueberry pie is left.
6x−12+2x=3+8x−15
Simplify:
6x+−12+2x=3+8x+−15
(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)
8x+−12=8x+−12
8x−12=8x−12
Subtract 8x from both sides.
8x−12−8x=8x−12−8x
−12=−12
Add 12 to both sides.
−12+12=−12+12
0=0
The real numbers are the only solution we can have.
