The answer is 21
3x7 is like 3 groups of 7
111111111
111111111
111111111
3 groups of seven if you count it up is ...
21i think 27
the answer is not 27. it is 21. write it down for your math homework.
The 27 your thinking is 9x3 not 7x3. because 7x3 is 21
7x3 is equal to 21.
here's an example: {7x5} + {7x3}
21
The polynomial 7x3 + 6x2 - 2 has a degree of 3, making it cubic.
the answer is 21 3 x 7 = 21
9
7x3=42
7x3-5x4=(7x3)-(5x4)=(21)-(20)=1 I used the order of operations rule, PEMDAS
x2 × 7x = 7x3
1x21 7x3
7x3=21
7x3=21
