Answer 1

Answer:

1. x = 4
2. $2^2*3*7$

Step-by-step explanation:

First, we add 16 and 28 $16+28=44$

Now we have to solve for x

We know we have to do parenthesis first so $(4+7)=11$

$44=x(11)$

Then we divided both sides by 11

$\frac{44}{11} =\frac{11x}{11}$

$x=4$

To find the Prime Factorisation of 84 we have to divide 84 by the smallest prime number which is 2

So $\frac{84}{2} = 42$

Since 42 is an even number we can still divide it by 2

So $\frac{42}{2} = 21$

Now we can divide 21 by the 2nd smallest prime number which is 3

So $\frac{21}{3} = 7$

So the prime factors of 84 would be $2*2*3*7$ or $2^2*3*7$
