Answer:
A. Yi did not list all the factors of 63
Step-by-step explanation:
Did the quiz
see explanation
The error is that the factors of 3 and 21 are missing from the list for 63
Factors of 42 : 1, 2, 3, 6, 7, 14, 21, 42
Factors of 63 : 1, 3, 7, 9, 21, 63
common factors are : 1, 3, 7, 21
greatest common factor = 21
A
v - 2u
= < - 2, 4 > - 2 < 2.5, - 4 > ← multiply each component by 2
= < - 2, 4 > - < 5, - 8 > ← subtract corresponding components
= < - 2 - 5, 4 + 8 > = < - 7, 12 >
Graph A shows the resulting vector
ok first you do the small one. 13 * 5 * 1/2 = 32.5 then you do 35 *1/2=17.5. you then divide 32.5/17.5=1.86
9+x<12
add 9 to an unknown number.
9+x
use the < less than symbol (instead of an equal sign) and write 12.
4.6
28.888 / 3.14 = 9.2
9.2 / 2 = 4.6
