Answer:
is this a question?
Step-by-step explanation:
Let's solve your equation step-by-step.
4(2x+8)=10x+2−2x+30
Step 1: Simplify both sides of the equation.
4(2x+8)=10x+2−2x+30
(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)
8x+32=10x+2+−2x+30
8x+32=(10x+−2x)+(2+30)(Combine Like Terms)
8x+32=8x+32
8x+32=8x+32
Step 2: Subtract 8x from both sides.
8x+32−8x=8x+32−8x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0
Answer:
All real numbers are solutions.
The sum of first 46 positive and odd numbers is 2116
<em><u>Solution:</u></em>
Given that we have to find the sum of first 46 positive and odd numbers
<em><u>The sum of first "n" natural odd numbers which are positive is given as:</u></em>

Here, n = 46
Therefore,
sum of first 46 positive and odd numbers = 
sum of first 46 positive and odd numbers = 
Thus the sum of first 46 positive and odd numbers is 2116
