Step-by-step explanation:
''All prime numbers are odd."
That is incorrect because if we consider the smallest odd number, 2, is an even number. We can say that except 2, all prime numbers are odd.
14. section is wrong. For example, both numbers can be negative, so when we multiple these two, it will equals a positive value.
Answer:
(k + 9)(k - 8)
Step-by-step explanation:
Given
k² + k - 72
Consider the factors of the constant term ( - 72) which sum to give the coefficient of the k- term ( + 1)
The factors are + 9 and - 8, since
9 × - 8 = - 72 and 9 + 8 = + 1, hence
k² + k - 72 = (k + 9)(k - 8)
