Hi there!

There are a few rules for multiplying positive and negative numbers:

-Any negative number times a negative number is a positive.
-Any positive number times a negative number is a negative.
-Any negative number times a positive number is a negative.
-Any positive number times a positive number is a positive.

So, using these rules, let's work through the multiplication:

-19 is a negative, and multiply by +2, would be a <u>negative</u>.
Multiply a negative by +37, and you still have a <u>negative</u>.
Multiply a negative by -0.8, and you will have a <u>positive</u>.
Multiply a positive with -112, and you will get a <u>negative.

So, your answer would be a negative number.

</u>Hope this helps!

For each sentence below, find the value of x that makes each sentence true.

vitfil [10]

<u>ANSWER</u>

1. $x=\frac{1}{2}$

2. $x=1$

<u>QUESTION 1</u>

The first sentence is $(5^{\frac{1}{5}})^5=25^x$ .

Recall that;

$(a^m)^n=a^{mn}$

We simplify the left hand side by applying this property to get;

$5^{\frac{1}{5}\times 5}=25^x$ .

$\Rightarrow 5^{1}=25^x$ .

We now rewrite the right hand side too in an index form to obtain;

$\Rightarrow 5^{1}=5^{2x}$

We now equate the exponents to get;

$\Rightarrow 1=2x$ .

$\Rightarrow \frac{1}{2}=x$

$\Rightarrow x=\frac{1}{2}$ .

<u>QUESTION 2</u>

The second sentence is $(8^{\frac{1}{3}})^2=4^x$

We simplify the left hand side first to get;

$(2^{3\times \frac{1}{3}})^2=4^x$

$2^2=4^x$

We now rewrite the left hand side too in index form to obtain;

$2^2=2^{2x}$

We equate the exponents to get;

$2=2x$

This implies that;

$1=x$

or

$x=1$

We need the length of the sides.
AB=√(2-(-2))²+(4-1)²=√16+9=√25=5; BC=√4²+0=4; CA=√0+9=3. AB+BC+CA=5+4+3=12.
