Product of complex numbers (-3i +4) and (3i +4)
(x - y)(x + y) = x² - y²
(-3i +4)(3i +4) = (4 -3i )(4 + 3i) = 4² - (3i)² = 16 - 9*(-1)=16 + 9 = 25
Answer:
Part A- yes, because all 3 sides are Equal (each side is 5)
Part B- yes, each rectangle has the dimensions 12*5
Part C- yes- since the sides are 5 and 12 you can determine that the diagonal is 13, using they Pythagorean theorem 
- true statement, so the lateral sides are rectangles, because the corners are 90
Part D-
(it is a 45-45-90 triangle- so the hypotenuse is the side length times 
Part E- the diagonal face as the largest area- dimensions are 
the area would be 
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
so d=rt is the famous formula.
30= 10r
so it would be 3 pages per minute
If I’m not mistaken it should be 8x+25. :)
Hope this helps!
Answer:
C.
Step-by-step explanation:
The relationship is proportion if y/x is constant.
So it is C because 12/4 = 15/5 = 18/6 = 3.
