Let u = < -6, 3> , v = < 1, 9> . find u - v.

a. < -15, 2>
b. < -9,-8>
c. < -5, 12>
d. < -7, -6>

let u = < -6, 1> , v = < -5, 2> . find -4u + 2v.

a. < 34, -8>
b. < 14, 0>
c. < 14, 3>
d. < 44, -12>

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

pls mark as brainliest.

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
