Pls answer this for me, this is the remainder theorem for grade 9 so help me.
scZoUnD [109]
1) Let f(x) be x^3+5x^2+2x+1
Since f(x) is divided by x+1,
R= f(-1) = (-1)^3 + 5(-1)^2+2(-1) + 1
= -1+5-2+1
= 3
2) Let f(x) be x^3 - 6x + 5x +2
Since f(x) is divided by x-5,
R= f(5) = x^3 - 6x^2 + 5x +2
= 5^3 - 6(5)^2 + 5(5) +2
= 125 - 150 + 25 + 2
= 2

Anmol got 60 marks out of 80 marks in mathematics what percent marks did he get​
Kay [80]

Answer:

75%

Step-by-Step Explanation:

There are two ways to go about this.

1) We can simply put it as a fraction = 60/80.

  Then since a fraction sign also means division, we divide 60 by 80 = 0.75

  Then to change a decimal into a percentage, we multiply by 100% = 75%

  So our answer is 75%

2) We can simply it after it is put into a fraction = 60/80 = 3/4

   It should be common knowledge that 3/4 is 75% depending on what                 grade you are in.

But there you have it, whichever way you prefer, the answer is always 75%.

Divide by 5 each side
X+2=4
Subtract 2 from each side
X=2

5(2+2)=20
Does work


In algebra when isolating (leaving alone on one side) x, you do the opposite operation, thus multiplying when you are trying to get rid of a division and vice versa
