Answer:
100
Step-by-step explanation:
To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:
when the quadratic is in standard form.
In this case, we would divide -20 by 2 and square it
-20/2 = -10
(-10)^2 = 100
Answer:
3 raise to -7 ÷3 raise to -10 × 3 raise to -5
3 raise to -7-(-10)×3 raise to -5
3 raise to 3×3 raise to -5
3 raise to 3+-5
3 raise to -2
1/3²
1/9
hope it helps you!
Step-by-step explanation:
First, let us find the magic sum in each row/column/diagonal.
Sum of numbers from 1 to 9 = 45.
45 divide by 3 rows = 15 each row.
The magic sum is 15.
For the diagonals, we have:
8 + 5 + x = Magic sum = 15,
6 + 5 + y = Magic sum = 15.
Therefore x = 2 and y = 4.
