Answer:
x^3 - 3x^2 + 5x - 15
x^2(x-3) +5(x-3)
(x^2 + 5)(x - 3) <==Answer
Step-by-step explanation:
54/4.5 = 12
Set it up as long division, with 54 "inside" the division sign and 4.5 outside. Then you have to move the decimal on 4.5 to the right once, which will give you 45 on the outside. You also have to move the decimal over 1 more place on the 54, which will give you 540 on the inside. Then figure out how many times 45 can go into 54, which is once. Then subtract 45 from 54, which will give you 9. Then you are left with 90 on the inside and 45 goes into that 2 times.
Answer:
First you must identify the inputs and output values and then you must check to see if each input value is paired up with only one output value and if so the table will be represented as a function.
Step-by-step explanation:
Identify the inputs and output values of the graph
Check to see if the values are paired up with one output value
To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5
He had 28.5kg but then he sold 16.93kg so that would be 28.5kg - 16.93kg which is 12.57kg, and then he sold another 9.807 so you do 12.57 - 9.807 which is 2.763kg. Are you sure this is middle school maths and not primary school?
