The sum is the total of the given values being added.
Given the expressions above, to add them, you just have to add the numbers with the same terms. 13x2 and 8x2 have the same terms which is x2, therefore, you can add both and the result is 21x^2 then just copy 5x so the sum would be 21x2 + 5x. Hope this answer helps.
Answer:
2.4 or 2 2/5
Step-by-step explanation:
When you multiply 12/15 and 3 you get 2.4 or 2 2/5
(-2 1) if u look at it this what you get
Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x +2x
__________
-3=6x-15
add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15
__________
12=6x
divide both sides by 6 to get 'x' alone
12=6x
/6=/6
_____
2=x
so your answer is 2=x or you can flip it and it will be the same, x=2
