Answer:
i is always positive
Step-by-step explanation:
if be multiply 3 by 3 and get 9, then you multiply -2i by 2i and get -4i squared
9-4i^2 is now easy to solve unless we do now know the value of i, but since i is squared, i is always positive

The Correct option is ~ B


Let's find the slope (m) using points (2 , 1) and (0 , -3)
hence, slope = 2
now, by Observing the given graph we can infer that the given line cuts the y - axis at point (0 , -3), so value of y - intercept (c) = - 3
[ y - coordinate of a point when x - coordinate is equal to 0 is the value of y - intercept of a line ]
And, we know the general equation of line in slope - intercept form is ~
now, let's plug the value of slope (m) and y - intercept (c) in the general equation to find the equation of line in slope intercept form ~
Answer: (4x + 5y)^2
Factor the expression.
Answer:
D
Explanation:
When u try to find the lengths of a right triangle you use the formula c = √(a² + b²). When you use the formula you take your TWO smallest numbers which is 12.5 and 30 you would plug it in the formula and solve and when you solve you should get 32.5. I checked my answer on a calculator to make sure it was right so js look at the picture below : )
