The error is that 9 shouldnt be written as nine it should be written as 3x3 or 3^2. So the answer should be 2^3 x 3^2 because 9 can be divided into even more prime factors of 72.
I=PRT
P=present amount
R=rate
T=time
basically
20+interest<u /> is more than or equal to 400
20+I<u>></u>400
minus 20 both sides
I<u>></u>380
solve
P=20
R=3%=0.03
T=?
I=PRT
380<u><</u>I=PRT
380<u><</u>20(0.03)(T)
380<u><</u>0.6T
divide both sides by 0.6
633.33333<u><</u>T
633.33 years at least
You multiply 9×7 then you add 1045 and 1125 when you get the answers of 9×7 and 1045+1125 you add them that is your answer
Hi!
<h3>We need to isolate x on both sides, and whatever we do to the equation we have to do to both sides. </h3><h3>First, add 8 to both sides. </h3>
2x - 8 + 8 = -6 + 8
2x = 2
<h3>Divide by 2 on both sides</h3>
2x/2 = 2/2
<u>x = 1</u>
<h2>The answer is x = 1</h2>
Hope this helps! :)
