(-3 - 2i) x (-4+ 2i) if you simplify using FOIL you will get 16+2i
The answer is 7850 centimeters since 1m=100 cm. 78.5*100=7850
Answer:
$16
Step-by-step explanation:
20% is the same as 0.2 in decimal form, since its decreasing you multiply $20 by 0.8 to get 16. If it was increasing, it would be 20 times 1.2
Answer:
1) The value of
is 12.
2) The length of the diagonal is 49.
Step-by-step explanation:
1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:
(1)
We need some algebraic handling to determine the value of
:


![[5+(-2)] \cdot x = 36](https://tex.z-dn.net/?f=%5B5%2B%28-2%29%5D%20%5Ccdot%20x%20%3D%2036)


The value of
is 12.
2) If we know that
, then the length of the diagonal (
) is:


The length of the diagonal is 49.
