Answer:
50
Step-by-step explanation:
and 
can be expressed in complex form, with 
= i
= 
= 
× = 8i
= 
= 
× = 4i
the factors can then be expressed as
(6 + 8i)(3 - 4i) ← expand using FOIL
= 18 - 24i + 24i - 32i² [ i² = ( )² = - 1 ]
= 18 - 24i + 24i + 32 ← collect like terms
= 18 + 32 + 0
= 50
1360÷282 = 4.82

The dead sea is 5 times more deep than the death valley.
Answer: C
Step-by-step explanation:
The best way to solve this is to replace the numbers and solve. The first number in an ordered pair is the x-value and the second is the y-value. So, you are replacing the X in each situation with the first number in these ordered pairs and seeing if the answer is what is the second value.
For A, you get (-2)(1)-1. This equals -3. This is not correct.
For B, you have -1+5, which is 6. This is also incorrect
For C, you have -1+2, which is 1. For the second ordered pair, 3+2. This is also correct.
Answer:
x = 30
Step-by-step explanation:
15 = 1/2x
multiply both sides of equation by 2
30 = x
