Complete the square to form a perfect square trinomial x^2-14x+
1 answer:
Answer: x^2 - 14x + 49 Explanation: 1) Divide the coefficient of x by 2: 14 / 2 = 7 2) so you have to add 7^2 = 49 x^2 - 14x + 49 3) that trinomial is equivalent to: => (x - 7)^2 4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2 (x - 7)^2 = x^2 - 14x + 49 Then you have to add 49 to complete the square. and form a perfect square trinomial.

Answer:
C. 1/16
Step-by-step explanation:
The probability of picking a blue envelope is 2/8 = 1/4. You want to select a blue envelope twice with replacement so we multiply 1/4*1/4 which is 1/16.
You would do 69sq×3.1416. that gives you 14,957.1576 round it to the nearest hundreth, 14,957.16

Answer:
B: 60
Step-by-step explanation:
f(x)= 5x+10, if x=10
f(10)=5(10)+10
5(10)+10=60
f(10)=60
