The factors of a number are <em>all of the positive whole numbers that go into it evenly</em>. For example, 2 is a factor of 6 because 6 ÷ 2 = 3, or equivalently, 6 = 2 x 3. Note that this naturally implies that every whole number has 1 and itself as a factor.
The numbers that go evenly into 24 are 1, 2, 3, 4, 6, 8, 12, and 24. For 27, those numbers are 1, 3, 9, and 27.
The <em>common factors </em>between two numbers are numbers that go into <em>both </em>numbers evenly. Looking through the lists for 24 and 27, we see that 1 and 3 are their common factors. The <em>greatest</em> common factor is, of course, the largest of these, so the greatest common factor of 24 and 27 is 3.
Answer:
Step-by-step explanation:
Multiply the equations together
(5x+4)(5x^2-7x-2)
25x^3-35x^2-10x+20x^2-28x-8
Add like terms
25x^3-15x^2-38x-8
Answer:
1.) D
2.) B
3.)
a.) 7x-34
b.) x (division symbol) 45 + 6
4.)
a.) x decreased by 216
b.) the quotient of 15 and x
Answer:
a) 3x - 6x^2y + 2xy - 2x
b) 4x^2 <u>- 3y </u>+ 2x <u>+ 7y</u>
Step-by-step explanation:
Like terms is when the terms are the same.
For example, 3x and -2x would be like terms (both have x).
Not like terms would be 4x^2 and +2x (one is just an x and the other is x^2).
Answer:Write 9/20 as a percent. Use equivalent fractions: 9/20 = 45/100 = 45%.
