a. Answer: m = 2
<u>Step-by-step explanation:</u>
f(x) = x² - 4x + 1
f(m) = m² - 4m + 1 = -3
m² - 4m + 4 = 0
(m - 2)(m - 2) = 0
m = 2
***************************************************
b. Answer: k = 2 and k = 5
<u>Step-by-step explanation:</u>
f(x) = x² - 7x + 14
f(k) = k² - 7k + 14 = 4
k² - 7k + 10 = 0
(k - 2)(k - 5) = 0
k = 2 k = 5
Answer:
45
Step-by-step explanation:
6 to the power of 2 + 3 to the power of 2
6² + 3²

Answer:
<h2>A. Agree, 4 children is the most typical number of children.</h2>
Step-by-step explanation:
By analysis the problem, we can make our decision by first determining the percent of 3.55 of 4
therefore the percentage can be computed as
=(3.55/4)*100
=0.8875*100
=88.75%
The analysis above it shows that 88.75 percent of the women who give birth to children give birth to 4 children.
This number is very close to a hundred percent hence the statistical claim is "Agree, 4 children is the most typical number of children."

Step-by-step explanation:
12. 4√3-√12+√18
4√3-2√3+√18
2√3+√18

13.(2√12-3√1/3)√6
(4√3 - 3√(1/3))√6
4√18 - 3√(6/3)
