Hi there!

First, the area cannot be 15×8, or 120 cm^2, because this isn't a normal rectangle.

We can get our answer to what the length of the odd-looking lines are by seeing that the length of the top line of the cutout is equal to half of the 8 cm^2 line. Half of eight is four, so each line in the square cutout is a length of four.

So, our diameter is 15+8+8+4+4+4+4+4, or 52 cm^2.

Here is where even I'm getting stumped!

I think the answer is 100, because if you subtract 15×8=120 and subtract 4 (the length of the small sides) × 5 (the amount of them) you get 100 cm^2.

Try it, and see if it works!

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer. I want to be able to assist more users one-on-one, as well as to move up in rank! :)

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The expression:

= \rm (\dfrac{x^4a^2b^3}{x^{-2}ab^2})^3

After using the integer exponent property:

\rm =\dfrac{x^{12}a^6b^9x^6}{a^3b^6}

= a³b³x¹⁸ Or

=x¹⁸a³b³

Thus, the simplification form of the provided expression is x¹⁸a³b³ option

(d) x¹⁸a³b³ is correct.

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that
butalik [34]

Answer:

y=-\dfrac{153}{35}.

Step-by-step explanation:

The given equation is

0.15(y-0.2)=2-0.5(1-y)

Using distributive property, we get

0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)

0.15y-0.03=2-0.5+0.5y

0.15y-0.03=1.5+0.5y

Isolate variable terms.

0.15y-0.5y=1.5+0.03

-0.35y=1.53

Divide both sides by -0.35.

y=\dfrac{1.53}{-0.35}

y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}

y=-\dfrac{153}{35}

Therefore, y=-\dfrac{153}{35}.
