16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.
Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500
Answer: x = 5/2 = 2.5
Step-by-step explanation:
<u>Given expression</u>
2x (x + 3) = 2x² + 15
<u>Expand parentheses and apply the distributive property</u>
2x · x + 2x · 3 = 2x² + 15
2x² + 6x = 2x² + 15
<u>Subtract 2x² on both sides</u>
2x² + 6x - 2x² = 2x² + 15 - 2x²
6x = 15
<u>Divide 6 on both sides</u>
6x / 6 = 15 / 6
x = 15/6

Hope this helps!! :)

Answer:
Its false because
Step-by-step explanation:
3250-1250=1500+2.(1250-500)

2000 = 1500 + 1500
2000 != 3000
Obviously 2000 isnt the same of 3000
