Answer:
A and B are correct
Step-by-step explanation:
Answer:
dimensions = 10.8 X 4
Step-by-step explanation:
Breadth/ width of room = x
Length of room = 6.8 + x
perimeter = 2 ( L + B )
29.6 = 2 ( 6.8 + x + x )
29.6/2 = 6.8 + 2x
14.8 - 6.8 = 2x
8 = 2x
8/2=x
4=x
Length of room = 6.8 + x = 6.8 + 4 = 10.8 m
Breadth/ width of room = x = 4m
Answer:
n = 0, n =2
Step-by-step explanation:
Given
(n + 1) + 3(n - 1) = 2(n - 1)(n + 1) ← distribute parenthesis on both sides
n + 1 + 3n - 3 = 2(n² - 1), that is
4n - 2 = 2n² - 2 ( subtract 4n - 2 from both sides )
0 = 2n² - 4n ← factor out 2n from each term )
0 = 2n(n - 2)
Equate each factor to zero and solve for n
2n = 0 ⇒ n = 0
n - 2 = 0 ⇒ n = 2
Answer:
B. Graph of a one-to-one function.
Step-by-step explanation:
A one-to-one function will have a unique value, y, for each different value of x. The graph displayed will have values very, very close to each other as x approaches ±4, but they won't be the same even at higher values of x.
9x + 27
-2y + 20
4x - 24
30x + 12xy
15x + 2 (?)
