Answer:
(-2, -1), (1, 2)
Step-by-step explanation:
The only integer divisors of 2 are 1 and 2. (2 is a prime number, divisible only by 1 and itself.) When listed according to the instructions, they can be positive or negative:
2 = (-2×-1) = (1×2)
Pairs of integer factors are (-2, -1) and (1, 2).
Answer:
N = 22.5
Step-by-step explanation:
N/6 = 15/4
Using cross products
4N = 6*15
4N = 90
Divide each side by 4
4N /4 = 90/4
N = 45/2
N = 22.5
Answer:
Expression = -23 + 26i
Step-by-step explanation:
Given the following data;
x = -5 + 6i
y = 3 - 2i
Expression = 4x - y
Substituting the values of "x" and "y" into the equation, we have
4(-5 + 6i) - (3 - 2i)
Expanding the bracket, we have;
Expression = -20 + 24i - 3 + 2i
Expression = -23 + 26i
