E would be your answer because the two negatives become a positive
Hello,
17/4π rad = (4π+π/4 )rad
17/4 π mod 2π = π/4 (rad) or 45°
To express (32+56) as a multiple sum of whole number we proceed as follows;
32=2*2*2*2*2=2^5
56=2*2*2*5=(2^3)*5
Thus;
(32+56)
=2^5+2^3*5
=2^3(2^2+5)
The answer is:
2^3(2^2+5)
Answer:
You should add .
Step-by-step explanation:
In order for + _ to equal 4, the numerator would have to equal 6 times the denominator after you add the number.
The denominator is 4, so the numerator should be 4 × 6, which equals 24. You should add something to make the numerator equal 24 and keep the denominator 4.
number = (24 - 23)/4 = 1/4
You should add .

When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²
