Answer:
Step-by-step explanation:
The fractions need a common denominator before you can add them together.
The least common denominator is 15bc.
The digit '1', the first copy of '1', is in the ten thousands place. To the right of this digit is 3. Since 3 is not 5 or larger, we simply change everything after the '1' to zeros
So we go from 413,125 to 410,000
The final answer is 410,000
3u + 21 divide 3 by both sides and your answer would be u= 7 :)
Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:
2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326
So the surface area of the prism is 326m²
