Answer:

(A)

Step-by-step explanation:

Tamika's work is wrong as:

The given equation is:

\frac{18a^{-5}b^{-6}}{30a^3b^{-5}}

She added the components, while the components must be subtracted in this equation, thus the equation becomes

=\frac{3a^{-5}a^{-3}b^{-6}b^5}{5}

=\frac{3a^{-8}b^{-1}}{5}

=\frac{3}{5a^8b}

which is the required simplified form.

Thus, the option A is correct.

Answer:

y = x - 10

Step-by-step explanation:

10 less than x would be written as x - 10, and subtracting 10 from x would ensure y (the output) is always less than the number you put in for x

Alisiya [41]

Answer:

A. The value of x is 5

B. The length of each side is 20!

Step-by-step explanation:

For part A., We can determine x by setting these equations to equal each other (as we know that all sides of a square are equal)! See below for how to:

4x = 2x +10\\2x = 10\\x=5

For part B. sub x for 5 to get the side length of one side...

4(5) = 20\\2(5) +10=20

We already know that all sides are equal, so the side length of each side is 20!

PLEASE HELP!! THANKS!<br><br> What is the 4th term in the sequence?
Anit [1.1K]

Answer:

b(4) = -405

Step-by-step explanation:

The first term of the sequence has been represented by 15.

The common ratio is -3

Since the first term is 15 you would have to multiply by -3 to find the next three terms.

B(1) = 15

B(2) = -45

B(3) = 135

B(4) = -405

The fourth term is -405

Answer:

-405
