Okay so i cant figure out the first one, but the second one looks like -7:3
Interest gained for a particular period equals to Money invested (kept) in Savings account for that period <em>multiplied by </em>Interest accrued on this money.
Therefore, Accrued interest i(x) = h(x) * s(x) = 200 * [ (1.05)x - 1 ],
where x is the number of years for which money is invested.
So, new function i(x) = (210)x - 200 .
The volume of a room = length * width * height
=12z³-27z
And by the analysis:
The volume = 12z³-27z
= ( 3z ) ( 4z²-9 ) ⇒ by taking (3z) common
= ( 3z )( 2z+3 )( 2z-3 ) ⇒ <span>the difference between two squares
So </span><span>the dimensions of the room will be 3z , 2z+3 , 2z-3

I have attached tha problem

So for this, we will be applying the <u>zero product property</u>, which is <u>"if a x b = 0, then either a = 0 or b = 0 or both a and b = 0"</u>. In this case, a = x + 13 and b = x - 7. Solve them separately:

<u>Your answer is x = -13 and 7.</u>
