Answer:
12 centimeters
Step-by-step explanation:
The triangle is half of an equilateral one. So the hypotenuse is double the minor leg
12 centimetres
Answer: I dont understand.
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
Since both equations give y in terms of x, equate the right sides
3x - 28 = - 2x + 22 ( add 2x to both sides )
5x - 28 = 22 ( add 28 to both sides )
5x = 50 ( divide both sides by 5 )
x = 10
The answer is complex number
a complex number is 2 parts
1. the real part
2. the imaginary part
the real part is the 'a' part of the a+bi
the imaginary part is the 'bi' part of the a+bi
answer is A
(B means exponent is no higher than 1, C means exponent is 2, D means b^2-4ac)
answer is A
