Using the given equation of,
                              V = lwh
The volume of the given prism in the figure is,
                              V = (x² - x / 4x + 1) (2x - 5)(24x² + 6x / x - 1)
By factoring,
                            V = ((x)(x - 1) / (4x + 1))(2x - 5)((6x)(4x + 1) / (x - 1))
Eliminating terms appearing in both the denominator and numerator,
                           V = (x)(2x -5)(6x)

Answer:Write 2x – 5 over 1.


Factor numerators and denominators, when possible


Divide out common factors to simplify.


Determine that the volume is (x)(6x)(2x – 5)


Step-by-step explanation: Because it is the right answer

!!!!!!! Why isn't A the correct answer? I am having trouble to reason why A is wrong so please help if can!

Answer:

d.  x = -3

Step-by-step explanation:

<u />\sqrt{(x + 3)}÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u />\sqrt{(x + 3)} = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3

Solve:7 +42-32-32 = 14.3-2a +7<br> A = -3<br> A= 0<br> A= 3<br> no solution
madreJ [45]

Answer:

a = 18.15

Step-by-step explanation:

7+42-32-32=14.3-2a+7

Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.

Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)

  1. Parentheses
  2. Exponents
  3. Multiplication
  4. Division
  5. Addition
  6. Subtraction

-15=14.3-2a+7

After combining like terms on the left side, you get -15. Now combine like terms on the right side of the equation by adding 14.3 and 7.

-15=21.3-2a

Get -2a alone by subtracting 21.3 from both sides.

-36.3=-2a

Divide both sides by -2.

a=18.15

In this equation, a should equal \boxed{18.15}.
