All real numbers
distribute (x+6)(x+3) to get x^2+6x+3x+18
your equation now looks like this:
x^2+6x+3x+18= x^2+6x+3x+18
because the equations are equal, the answer is all real numbers
Answer:
The average density of the rod is 1.11 kg/m
Step-by-step explanation:
Linear density is given by the expression 10/(sqrt(x 1)) kg/m
x is said to be measured in meters from one end of the rod. Therefore x represents the length of the rod = 8 m
Substitute the value of x into the expression of linear density to determine the average density of the rod
Average density = 10/(sqrt(81)) = 10/9 = 1.11 kg/m
Divide the numerator by the denominator and any remaining values go back above the denominator.
Example:
17 / 4 is an improper fraction. To turn it into a proper fraction we do 17 divided by 4.
17 / 4 is 4 with a remainder of 4. So we put the 4 on the outside and the 1 back above the denominator, which is 4.
It ends up looking like this:
Answer:7
Step-by-step explanation:
150 divided by 24 equals 6.25 but round it up so everyone gets one.
Working backwards:
17-3=14
14/2=7
7 is the second term in the sequence. Continue backwards.
7-3=4
4/2=2
2 is the first term in the sequence, aka your answer.
