Select all of the true statements (there may be more than one correct answer).
a. {a1,a2,a3} is a linearly independent set
b. {a1,a2} is a linearly independent set
c. {a1,a2,a3,a4} is a basis for r3
d. span{a1,a2,a3}=r3 e.
{a1,a2,a3} is a basis for r3 f.
span{a1,a2}=r3 g. {a1,a2,a3,a4} is a linearly independent set h.
span{a1,a2,a3,a4}=r3 i. {a1,a2} is a basis for r3

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
