Answer:
The answer is square root 72 or if you don't want to put it under the square root, just simplify and you get 8.49. Just use the distance formula.
MARK ME BRAINLIEST!!!
Since the signs are different, you have to subtract. 2
302.1 is the answer to the problem.
Answer:
z = 1, z = 9
Step-by-step explanation:
Given
z² + 9 = 10z ( subtract 10z from both sides )
z² - 10z + 9 = 0
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)
The factors are - 1 and - 9, since
- 1 × - 9 = 9 and - 1 - 9 = - 10, thus
(z - 1)(z - 9) = 0 ← in factored form
Equate each factor to zero and solve for z
z - 1 = 0 ⇒ z = 1
z - 9 = 0 ⇒ z = 9
