Step-by-step explanation:
Mr.Josol : what will be the height of the ball after 2 seconds?
you don't list any expressions to choose from but
if width = x
and length = 2x
Area = 2x * x
Area = 2x^2
The equivalent expression of
is 
<h3>How to determine the equivalent expression?</h3>
The logarithmic expression is given as:

The law of logarithm states that:
log(a) - log(b) = log(a/b)
This means that the expression can be split as:

Hence, the equivalent expression of
is

start by plugging in the value you already have, in this case, 5 for y.
-4x-3(5)=17
-4x-15=17
-4x=32
x=-8
however, since a is a+1, a would be 7 (making x 8)
also plz tell me if i read this wrong and it’s actually 1,5 rather than a+1 and 5 cause if i did i’m so sorry lol.
