Answer:
<h2>
9 weeks</h2>
Step-by-step explanation:
Sol had $1535 in his savings
has been spending $30 each week for guitar lessons.
If his current balance is $1265
find:
how many weeks has he been taking lessons?
$1535 - $1265 = $270
<u> $270 </u> = 9 weeks
$ 30 per week
It is in the ones and tens digit i think thats the answer
The answer is 7 because f is a denomination
Do you want us to simplify? If so, it would be 3/5
So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
