Mathematics
2 answers:
sasho [114]3 years ago
8 0

Area of trapezoid : (Base 1 + base 2) x h x 1/2

Let's solve!

( 2+6) x 5 X1/2

= 40x1/2

=20

20 in squared is the area!

Answer:

20 in.

Step-by-step explanation:

The formula for the area of a trapezoid is:

A= \frac{b1+b2}{2} (h)\\\\

A= \frac{6+2}{2} (5)

A= \frac{8}{2} (5)\\\\A= 4(5)\\\\A= 20

What is the solution for x in the equation -4+5x-7=10+3x-2x in a fraction
Alex

Answer:

x = 21/4

Step-by-step explanation:

re-arrange the equation

-4+5x-7-3x = 10-2x (move 3x to the other side)

-4+5x-7-3x+2x = 10 (move 2x to the other side)

5x-7-3x+2x = 10+4 (move 4 to the other side)

5x-3x+2x = 10+4+7 (move 7 to the other side)

4x = 21 (add up both sides)

x = 21/4 (divide both sides by 4

Find an equation of a degree 3 polynomial (in factored form) with the given zeros of f(x): − 3 , 4 , − 3 . Assume the leading co
oksano4ka [1.4K]

f(x) = x³ + 2x² - 15x - 36 is the equation of a degree 3 polynomial (in factored form) with the given zeros of f(x) are − 3 , 4 , − 3 assuming that the leading coefficient is 1. This can be obtained by formula of polynomial function.

<h3>Find the required equation:</h3>
  • The zeroes or roots of a polynomial function are x values for which          f(x) = 0
  • If the zeroes or roots are r₁, r₂, r₃,... then possible polynomial function is

⇒ f(x) =  a(x - r₁)(x - r₂)(x - r₃)

where a is the leading coefficient

Here in the question it is given that,

  • Polynomial should be with degree 3
  • zeros of f(x) are − 3 , 4 , − 3

By using the formula of polynomial function we get,

⇒ f(x) =  a(x - r₁)(x - r₂)(x - r₃)

⇒ f(x) = 1(x - (-3))(x - (4))(x - (-3))

⇒ f(x) = 1(x + 3)(x - 4)(x + 3)

⇒ f(x) = (x + 3)(x² - x - 12)

⇒ f(x) = x³ - x² - 12x + 3x² - 3x - 36

⇒ f(x) = x³ + 2x² - 15x - 36

Hence f(x) = x³ + 2x² - 15x - 36 is the equation of a degree 3 polynomial (in factored form) with the given zeros of f(x): − 3 , 4 , − 3 assuming that the leading coefficient is 1.

-y+8y=?<br> What is the answer please?
Tpy6a [65]

Answer:

y = -6/7

x = 6/49

Step-by-step explanation:

-7x -y = 0

7x +8y = -6

Add the two equations together to eliminate x

-7x -y = 0

7x +8y = -6

-----------------------

   7y = -6

Divide by 7

7y/7 = -6/7

y = -6/7

Now we need to find x

-7x -y = 0

-7x -(-6/7) =0

-7x +(6/7) =0

-7x +6/7 -6/7 =0-6/7

-7x = -6/7

Divide each side by -7

-7x/-7 = -6/7 *-1/7

x = 6/49
