I don’t know what your asking
Answer:
13<y+x<32
Step-by-step explanation:
It depends.
If x and y are Whole Numbers, it would be 14<y+x<31.
If x and y are Real Numbers, including decimals and fractions, it would be 13<y+x<32
Since it doesn’t specify, it’s probably the latter.
Answer:
A) 7x^3 + 13x^2 + 8x + 9
Step-by-step explanation:
(3x^2 + 2x + 7x^3) + (10x^2 + 6x + 9)
I like to line them up vertically
7x^3 +3x^2 + 2x
+ (10x^2 + 6x + 9)
-----------------------------------
7x^3 +13x^2 +8x +9
