So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice
Answer:
<u>400 miles</u>
Step-by-step explanation:
2 hours = 100 miles
Therefore, he will drive 4 times the distance given 4 times the time taken.
=> 100 x 4
=> <u>400 miles</u>
Answer:
<h3>
<u>X=5</u></h3>
Step-by-step explanation:
hope it helps....
5(2x + 6) = -4(-5 - 2x) + 3x
Distribute: 10x + 30 = 20 + 8x + 3x
Combine like terms: 10x + 30 = 20 + 11x
Simplify: 10x + 30 - 20 = 20 - 20 + 11x
Simplify: 10x - 10x + 10 = 11x - 10x
Divide for x: 10/1 = 1x/1
x = 10
5 1/2 * 1 2/5
They can be turned into improper fractions to make multiplying easier. Do this by multiplying the whole number by the denominator and then adding the numerator, and then putting that number over the given denominator.
11/2 * 7/5
The numerators are multiplied and the denominators are multiplied.
77/10
Now, reduce it back into a mixed number.
7 7/10
Hope this helps! :D
