Answer:
x = 9 and x = -1
Step-by-step explanation:
This equation should be written all on one line:
2(x - 4)^2 = 50
using " ^ " to denote exponentiation.
Dividing both sides by 2 yields
(x - 4)^2 = 25
We must solve for x - 4, and then for x alone:
Taking the square root of both sides, we get:
x - 4 = ±5
which yields two separate solutions: x = 9 and x = -1
Youn could test all of the options by putting 8 and 3 in for a and b.
A. a - b = 5
8 - 3 = 5
5 = 5
B. a + b = 5
8 + 3 = 5
11 ≠ 5
C. a - b = 8
8 - 3 = 8
5 ≠ 8
D. a + b = 8
8 + 3 = 8
11 ≠ 8
As you can see, the only one that works is A. a - b = 5.
Answer:
Errata is originally the plural of the singular Latin noun erratum. Like many such borrowed nouns ( agenda; candelabra ), it came by the mid-17th century to be used as a singular noun, meaning “a list of errors or corrections to be made (in a book).”
