The appropriate choice is
... D) x = -2 ±√7
I would say infinitely many
m^2 + 12m + 35
We can factor using the sum-product, when the sum of 2 numbers is 12 and the product of those 2 numbers is 35.
7+5 = 12
7 x 5 = 35
So we have the numbers 7 and 5.
m^2 + 12m + 35 = (m+7)(m+5)
Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular
