Answer 1

Answer: Least common denominator finds a common number in the denominator of two fractions. 14 can be factored out as 2*7 and 7 is obviously 7*1. So the least common denominator could come from both numbers that have common denominators. In order to attain a common denominator, you need to multiply the 7 by 2 to make 14. So the least common denominator is c. 14.

Answer 2

Answer: the correct answer for that is c. otherwise 14

Let f(x)=(8x^4-3)^3 and g(x)=8x^4-3 given that f(x)=(h g)(x) , find h(x)

Answers

Answer:

$h(x) = x^(3)$

Step-by-step explanation:

$f(x) = (8 * x^(4)- 3)^(3)$ ------------(1) (given)

$g(x) =(8 * x^(4)- 3)$ -------------(2) (given)

so,

f(x) = h(g(x)) (given)

= $(g(x))^(3)$ -----(from (1) and (2))

⇒ $h(k) = k^(3)$ -----(taking g(x) = k)

⇒ $h(x) = x^(3)$ is the function.

Ravi can type 6 words in 4 seconds. how many words can she type in 10 seconds.

Answers

If in four seconds, she can type six words, then we can guess that in eight seconds (4x2) she can type twelve words (6x2). Now, thats only for eight seconds, and we need two more to make ten. In four seconds, she types six words, so we need only two seconds, which would be half of six (3). And the 12+3 gives us 15 words in ten seconds. Sorry if its wrong, but hope i helped somehow :)

An equivalent expression for 9z+27

Answers

Answer:

=9(z+3)

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you had to rewrite the problem down of 27=9*3

$9z+9*3$

Then, you can also factor it out by the common term of 9.

$=9(z+3)$

Hope this helps!

Thanks!

-Charlie

Final answer:

The equivalent expression for 9z+27 is 9(z+3). By factoring out the greatest common factor, we can simplify the expression and represent it in a different form. For example, if z=5, then the original expression 9z+27 is equal to 72, which is also the value of the equivalent expression 9(z+3).

Explanation:

The equivalent expression for 9z+27 is 9(z+3).

To find the equivalent expression, we can factor out the greatest common factor of the terms, which in this case is 9. We can rewrite the expression as 9(z+3), where z+3 represents the remaining terms after factoring out 9.

For example, if z=5, then the original expression 9z+27 becomes 9(5)+27 = 45+27 = 72, and the equivalent expression 9(z+3) also becomes 9(5+3) = 72.
