Values of x
The given range implies that x is a prime number between 40 and 50 (inclusive)
From 40 to 50, the primes are: 41, 43 and 47
Hence:
Answer: its c
Step-by-step explanation:
because the situation describes two lines that have the same and different y-intercepts
Answer:
13 by 20 inches
Step-by-step explanation:
Represent the quantities as follows:
P = 2W + 2L
L = W + 7
Then P = 2W + 2(W + 7), or P = 4W + 14
and this formula has the value 66 inches.
Thus, P = 66 inches = 4W + 14 inches, or
52 inches = 4W
Dividing both sides by 4, we get W = 13 inches.
The width is 13 inches and the length is (13 + 7) inches, or 20 inches.
I think is
(x + y ) ( 2x - xy + 2y)
2x2 - x2y + 2yx + 2xy - xy2 + 2y2
