Answer:
(4+7i)(4-7i).
This is because you FOIL it to get:
16 + 28i - 28i -49i^2.
That equals to 16 - 49i^2, which equals to:
16 + 49
65, which is a real number.
Answer:-8
Step-by-step explanation:
Answer:
because, it will completely change the slope
Step-by-step explanation:
Let x units be the length of the shortest side of the triangle.
Perimeter of triangle = 2(x + 1) +x = 3x + 2
Perimeter of square = 4(x - 2) = 4x - 8
Equating the two expressions for perimeters, we get:
3x + 2 = 4x - 8
The solution is: x = 10
The answer is 10 units.
