Answer:
n=19
Step-by-step explanation:
Three less than twice a number is 35
2n-3 =35
add 3 to each side
2n-3+3 = 35+3
2n = 38
divide by 2
2n/2 = 38/2
n=19
Answer:
Step-by-step explanation:
We will solve this questions using some dimensionality analysis.
a) Note that 
is a vector space of dimension 4. So, given a set of three vectors, they could be or could not be linearly independent. However, if they were, they would not span since in order for us to span we need 4 or more vectors. Since a set of three vector cannot span this space, they automatically cant be a basis for .
b) 
has a dimension 3. So, for a set of vectors A to span this space, we need that A contains at least 3 vectors that are linearly independent. So A could have possibly infinite number of vectors as long as there is a subset of A that is composed by 3 linearly independent vectors.
If we work out this particular equation according to the acronym PEMDAS
(or parenthesis, exponents, multiplication, division, addition, subtraction) this can be easily done. The resulting equation would look
as follows PEMDAS2(3)2+16(2)+112+112+1=13
