A bag contains only red and blue marbles. There are a total of 36 marbles in the bag. There are 5 red marbles for every 4 blue m

Salsk061 [2.6K]

Answer:

let total no. of red marbles be x and blue marbles be y.

then according to first case

x + y =36

or,x=36 -y.....(i)

in case second

x/5 =y/4

or,x=5y/4......(ii)

then from equation i and ii, we get

36-y = 5y/4

or, (36-y)4 = 5y

or, 144 -4y =5y

or, 144 = 5y + 4y

or, 144 = 9y

or, 144/9 =y

or, y = 16

again x = 36 -y

here , y =16

so,

x= 36 -16

x= 20.

hence total no. of red marbles is 20 and blue marbles is 16 .

If Carls removes 1 blue marble from bag, there will be 15 marbles in the bag,

20÷5 is not equal to 15 ÷3 .

correct ratio of red and blue marbles is 20÷15=

4/3.

Express the polynomial below by nesting. f(x)=4x³+3x²+2x-4

BabaBlast [244]

Answer:

$f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Step-by-step explanation:

Considering the polynomial

$f(x)=4x^{3} +3x^{2} +2x-4$

Expressing the polynomial by nesting

So,

$f(x)=4x^{3} +3x^{2} +2x-4$

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

$4x+3$

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

$(4x+3)x+2$

Step 3) Repeating the previous step until all terms are within the equation.

So,

$((4x+3)x+2)x-4$

Therefore, $f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Keywords: polynomial, nesting form
