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
35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10 (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.
I don’t know what the possible answers are, but it could be any of the following.
8x8x8x8x8x8
(8^3)*(8^3)
Step-by-step explanation:
119°+29°+n°=180°. (Sum of all the angles of triangle)
So,
158°+n= 180°
n= 180°-158°
n= 22°
Answer:
$12000
Step-by-step explanation:
P=CRT
C=cost
R=rate
T=time
P=3000 x 8 x 50/100= $12000
