Find a b if a = (4,3) and b =(4,5).
a. 31
b. (8,8) -
C. (16,15)
d. -1

Given:

a=(4,3) and b=(4,5)

To find out:

a.b

Solution:

in case 1:

a=4 and b =4

so,a×b=>4×4=16

in case 2:

a=3 and b=5

so,a×b=>3×5=15

Therefore, C. (16,15) is correct options

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
