Which of the following subsets of P2 are subspaces of P2? A. {p(t) | p(3)=0} B. {p(t) | p(−t)=−p(t) for all t} C. {p(t) | p(0)=3} D. {p(t) | p′(t)+8p(t)+5=0} E. {p(t) | ∫60p(t)dt=0} F. {p(t) | p′(t) is constant }

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !

b is the right answer
