When estimating, you want to round the dividend and the divisor to the nearest time table number (i.e. 5700 --> 5400). Finding the quotient is easier when you estimate. Writing the remainder as a fraction is simple. First, get your remainder and your divisor, then make it to a fraction.
ex:
If you get a remainder of 3, and have a divisor if 12, your remainder would be 3/12, or 1/4.
Answer: 1, -1
Step-by-step explanation: This is a difference of squares when factored,
(x+1)(x-1)
Let's check using FOIL(First, outside, inside, last)
x * x =x^2
1 *x =x
x * (-1) =-x
1* -1 =-1
so x^2 +x -x -1
=x^2 -1
Answer:
<em>B + 21</em>
or
<em>21 + B</em>
Step-by-step explanation:
<em>The sum of B and 21 </em>
<u>The sum of</u> : means to add B and 21
The algebraic expression would be: B + 21 or 21 + B (depending on how you/your teacher wishes it to be written)
