Answer: 25
Step-by-step explanation:
Finding the product of complex numbers is not different to finding the product of real numbers
(-3i+4) * (3i+4) = -9i^2 + 12i - 12i + 16 = 25
Answer:
x=21
Step-by-step explanation:
1. 2x-2/5*5=8*5 Multiply the 5 on both sides to cancel out the denominator.
2. 2x-2+2=40+2 Add 2 on both sides to isolate the term with the variable.
3. 2x/2=42/2 Divide both sides by 2 in order to isolate the variable itself. Yay, you got the answer, 21!
Heyy I hope you have a great day, this took forever to type so it would be very appreciated if you marked this answer as brainliest... UwU
It’s will be 8 x 7 which is 56
A quadrilateral has 4 angles that add up to 360 degrees. So, to solve for x:
85+150+55=290
360-290= 70
X= 70 degrees
