Answer:
Lesser = -
- 7 = -10.317
Greater = + - 7 = -3.683
Step-by-step explanation:
I am assuming you are asking for the lesser x solution and greater x solution.
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x+7 = ±
x = ± - 7
Lesser = - - 7 = -10.317
Greater = + - 7 = -3.683

Answer:
The answer to your question is length = 6 in, # of pieces = 8
Step-by-step explanation:
Data
2 sandwiches one of 18 in and other of 30 in
cut into equal sections
To solve this problem, use the greatest common divisor, so find the prime factors of both numbers.
18 30 <u>2 </u> Only 2 and three are common factors, then
9 15 <u>3 </u> 2 x 3 = 6
3 5 3
1 5 5
1
The length of the sections will be 6 inches
How many sections will be? in the first 18/6 = 3 in the second 30/6 = 5
total = 8
