Answer:
A. None of the answers are correct
Step-by-step explanation:
∠3 is a verticle angle to ∠1
linear pair means they add up to 180
complementary mean they add up to 90
192x³ + 81
= 3(64x³ + 27)
= 3(4x + 3)(16x² - 12x + 9) ← answer
Answer:
90miles divided by 18 miles is 5 gallons
Division is the splitting of large numbers (in this case) numbers into equal groups of smaller numbers.
Here are some terms you need to understand before you divide:
The number being divided is called the <em><u>dividend</u></em>.
The number that you're dividing by is called the <u><em>divisor</em></u>.
The answer that you get to the division problem is called the <em><u>quotient</u></em>.
For example:
Let's try dividing 4 ÷ 2 .
Since 4 is the number being divided, it is the <em>dividend</em>.
And since were are dividing 4 (the dividend) by 2, 2 is the <em>divisor</em>.
We need to try and find the quotient to solve 4 ÷ 2 .
Think of it this way;
There are 6 cookies and we need to divide them equally so that 2 people can have the same amount of cookies.
6 ÷ 2 = 3
You know the answer is 3 because 2 goes into 6 three times. 2 × 3= 6 (Since you asked a question about division, I'm guessing you know multiplication.)
3 for one person and 3 for the other.
So how many does each person get? 3 cookies, fair and square.
A nice way to check this problems is fact families, as I have mentioned before with the multiplication problem.
Hope this helps!
