Answer:
12
Step-by-step explanation:
With PEMDAS you could know to do parentheses FIRST
6 x (10 - 2^3)
6 x (2)
12
We will break this down into its parts:
We know that this is a fraction where the numerator is √(-1) = i
The denominator:
4 - 3i - (2 + 5i); we put 2 + 5i in brackets because we are to subtract its quantity.
Simplifying the denominator:
4 - 3i - 2 - 5i
= 2 - 8i
Now, we write the expression in fractional form:
i / (2 - 8i)
To remove an imaginary number from the denominator, we multiply and divide by its conjugate. The conjugate of a + bi is a - bi
i(2 + 8i) / (2² - (8i)²)
= (-8 + 2i) / (4 + 64)
= -2/17 + i/34
Answer:
A. 1 centimeter
Step-by-step explanation:
To solve you could use a proportion, in this case, 2/8=x/4. You can cross multiply to find the value of x. 8x=2*4, then simplify, 8x=8. Finally isolate the variable by dividing by 8. 8x/8=8/8, simplified that equals x=1.
They are congruent to each other. Any two polygons with the scale factor of 1 will be congruent.
