Answer:
Step-by-step explanation:
We are asked to divide the first equation f(x) by the second equation g(x) and then multiply the division by x
We will be using the difference of two squares to solve this question somewhere in the process
(f/g) * x
(25-x^2) / (x+5) * x

10.28 , 28 cm in meters is 0.28. you have 10 meters therefore 10+.28= 10.28
What is the question here
Answer:
Step 2 has error and step 4 has error.
Step-by-step explanation:
Here we can see that elimination method is applied to solve the system of equations for which -2 is multiplied both sides of equation first
-2(x+2y)=-2(10 which is correct
but in step 2
left side is -2x-4y and the right side is -10 which has to be -20 which makes this step wrong and this is the error made by student.
in Step 4 also ,value of the y has to be 5 but student plugged y =1 which is also error by student.
Correct solution is
-2x-4y= -20
2x+ 5y= 15
on adding ,we get
y = -5
plugging y =5 in equation x+2y= 10 ,we get x+2(-5) =10 ,we get x = 20
therefore (20,-5) is the solution
