(a) the set r2 with the following addition and scalar multiplication operations on u = (u1,2) e r2 and v = (v1, 2) r2 (u11 u221 (ки, киз). ku u v= (b) the set p of all rcal-valucd polynomials (i. c. with real cocfficients) of degrcc less to n, and with standard polynomial operations of addition and scalar equa than or multiplication (c) check the axiom 6 for each of (a) and (b) with k complex, and conclude whether any of these sets is a complex vector space?

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

it’s supposed to be -4+45=41

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
