Which of the following polynomials has a remainder of 24 when divided by x+2?

Bad White [126]

Option C is the correct choice $-2x^4+4x^2+3x-2$ ,

Remainder of a polynomial by substitution

For a polynomial f(x) to give a remainder of 24 when divided by x + 2:

f(-2) = 24

By testing, substitute x = -2 into the equation $-2x^4+4x^2+3x-2$

$f(x) = -2x^3+4x^2+3x-2\\\\f(-2)=-2(-2)^3+4(-2)^2+3(-2)-2\\\\f(-2)=-2(-8)+4(4)-6-2\\\\f(-2)=16+16-8\\\\f(-2)=32-8\\\\f(-2)=24$

Since f(-2) = 24 when x = -2 is substituted into $-2x^4+4x^2+3x-2$ , then $-2x^4+4x^2+3x-2$ has a remainder of 24 when divided by x+2

56 thousandths - 23 thousandths=how many hundredths and thousandths?

alexandr1967 [171]

<span>56 thousandths - 23 thousandths=how many hundredths and thousandths?
Let us first solve this and get the difference of the given numbers.
=> 56 thousandths = 0.056 (there are 5 hundredths and 6 thousandths)
=> 23 thousandths = 0.023 (there are 2 hundredths and 3 thousandths)
=> 0.056 – 0.023 = 0.033 is the answer
there 3 hundredths and 3 thousandths value left after subtracting the given 2 decimal numbers.</span>

Find S in formula A=5²<br><br>Need help plss this for my exam

Kruka [31]

Answer:

S = √A

Step-by-step explanation:

Given that;

A = S²

Finding S implies making S the subject of the expression.

To do this;

A = S²

Take the square root of both sides of the expression;

√A = √S²

The square-root of the square of S = S;

S = √A

2. Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8mi^2 and th

CaHeK987 [17]

Step-by-step explanation:

Let length is x and breadth is y.

The formula for the area and the perimeter of a rectangle is given by :

A = xy

P = 2(x+y)

Here, A = 8 mi² and P = 16 miles

Putting all the values,

xy = 8

y=8/x ......(1)

2(x+y) = 16

x+y = 8 .....(2)

Put equation (2) in equation (1) as follows :

$x+\dfrac{8}{x}=8\\\\x^2+8=8x\\\\x^2-8x+8=0$

When we solve, we get :

x = 6.82 miles, 1.17 miles

Put the value of x in equation (1)

When x = 6.82 miles,

y = 8/6.82

y = 1.17 miles

When x = 1.17 miles,

y = 8/1.17

y = 6.82 miles

Hence, the dimension of the field is 6.82 miles and 1.17 miles.
