26. (4 points each) let a = span and b 4 3 (a) what is the angle betweenb and the first basis vector for a? (b) what is the angle between b and the second basis vector for a? (c) compute the projection of b onto a.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184
