What is the answer of 7 copies of the sum of 8/5 + 4
kotykmax [81]
To solve (8/5 + 4)7, you first have to add 8/5+4.  But you cannot simply add the too because they have to be in a common denominator 'form'.  To do that, we find a common denominator which is 5.  We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28.  You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1.  Another of saying 28/5 is 5 3/5.  So 5 3/5 x 7/1= 39 2/10 (final answer)

I need help how to solve it mot the answer plz and thank u
jek_recluse [69]
The second one would be the answer. You want to plug in for this question. You can divide over the five leaving you with (x-2)^2 =25. Since you are squaring this answer, you want to get either 5 or negative five. Both -3 and 7 will do that.
