Answer:
x = 4 and y = - 5
Step-by-step explanation:
note that the product of a complex number and it's conjugate is real
That is
(a + bi)(a - bi) where a, b are real
= a² - abi + abi - b²i²
= a² + b² ← a real number
For (4 + 5i)(x + yi) to be real
we require (x + yi) to be the conjugate of 4 + 5i , that is 4 - 5i
(4 + 5i)(4 - 5i) ⇒ x = 4 and y = - 5
Answer:
<u>x = 114</u>
Step-by-step explanation:
180 - 66 = x
x = 114
Have a nice day!
If by that you mean
24x^3 and 14x^2 × y^2,
The Gcf between them is
2x^2
Proof: 24x^3/2x^2 = 12x
(14x^2 × y^2)/2x^2 = 7y^2
since there is no common factor between 12x and 7y^2, 2x^2 is the greates common factor
No. Because the Tenths place is right after the decimal. So he will only have 1 decimal place. Welcome!
