What are the zeros of the function? h(x)=x^3−2x^2−3x
maksim [4K]
To find the zeroes you make the function equal to zero and then solve. 
0=x^3-2x^2-3x
Then factor out the x to get a quadratic inside the parentheses.
 0=x(x^2-2x-3)
Factor the inside quadratic formula.
x(x^2-2x-3)=x((x-3)(x+1))
Lastly, use the zero product property to solve.
x*(x-3)*(x+1)=0
x=0,x=3,x=-1

7. What's the perimeter of a rectangle with length 12 m and width 5 m?
azamat

Answer:

Option(c) 34m

Step-by-step explanation:

Perimeter of a rectangle = 2(length + breadth)

length = 12m

breadth/width = 5m

Perimeter = 2(12 + 5)

                = 2(17)

                = 34m

What is (43/7÷ x+32/9) ÷25/6=4/3
Fittoniya [83]

The value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14

<h3>How to solve for x in the equation?</h3>

The equation is given as:

(43/7 ÷ x + 32/9) ÷ 25/6 = 4/3

Rewrite as a product

(43/7 ÷ x + 32/9) x 6/25 = 4/3

Multiply both sides of the equation by 25/6

(43/7 ÷ x + 32/9)= 4/3 x 25/6

Evaluate the product

(43/7 ÷ x + 32/9)= 50/9

Rewrite the equation as:

43/7x + 32/9= 50/9

Subtract 32/9 from both sides

43/7x = 2

Multiply both sides by 7x

14x = 43

Divide by 14

x =43/14

Hence, the value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14
