Answer:
B. <2,-5>
Step-by-step explanation:
We are given the vectors,
u = <-2,0> and v = <4,-5>
It is required to find the sum of the vectors i.e. u + v.
So, we have,
u + v = <-2,0> + <4,-5>
i.e. u + v = < -2+4 , 0-5 >
i.e. u + v = <2,-5>
Thus, the sum of the vectors written as ordered pairs is <2,-5>.
Hence, option B is correct.
Answer:
16s^2 -9
Step-by-step explanation:
(4s+3)(4s–3)
FOIL
first : 4x*4x = 16s^2
outer -3 *4s = -12s
inner 3*4s = 12s
last = 3* -3 = -9
Add them together
16s^2 -12s+12s -9
Combine like terms
16s^2 -9
