Answer:
25
Step-by-step explanation:
3 x 3 = 9
4 x 4 = 16
9 + 16 = 25
In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
The question mark is 100. It is a variable if you don't know
To find a percent you multiply the decimal number by 100. OR to be easier just move the decimal number 2 places to the right.
4.3%
