use FOIL (first, outside, inside last)
4a * 3a = 12a²
4a * -8 = -32a
-6 * 3a = -18a
-6 * -8 = 48
-12a² - 32a - 18a + 48
combine like-terms: -12a² -50a + 48
Answer:
4/24
Step-by-step explanation:
Because 1/6 is 4/24 simplified.
To prove this, all you have to do is try simplifying 4/24 yourself. To do that, we are going to use 4 to divide both the numerator and the denominator because 4 is a common factor of 4 and 24.
(To simplify a fraction, you divide both the numerator and denominator by a common factor)
So 4 divided by 4 is 1, and 24 divided by 4 is 6
1/6
Let's have the first number, the larger number, be <em>x</em>. We'll have the second, smaller number be <em>y</em>.
We know that x = y + 6, since x is 6 greater than y.
We also know that 330 = x + y.
Because x = y + 6, 330 = y + 6 + y, which simplifies to 330 = 2y + 6.
Now all we need to do is simplify the equation. First, we subtract 6 from both sides:
330 - 6 = 324
2y + 6 - 6 = 2y.
So we have 324 = 2y. Then we divide both sides by 2 to get:
162 = y
Plug in y = 162 into the equation x = y + 6 to get:
x = 162 + 6
x = 168
Let's check to make sure our answer is right. 168 is 6 more than 162. 162 + 168 equals 330. So our two numbers are 168 and 162.
