Answer:

Step-by-step explanation:

1. 6*6 + 6*12

= 36 + 72

= 108.

2. 3*5 + 3*5 + 3*14

= 15 + 15 + 42.

= 72.

3.  10*4 + 1/2 * 4*4

= 40 + 8

= 48.

4. 12*6 + 1/2 * 12 * 3

= 72 + 18 = 90.

Find the value of the expression if x=-7
LUCKY_DIMON [66]

Answer: -16

Step-by-step explanation:

49 would be the result of -7 squared. Due to the fact it is negative, it would cancel out to be positive.

For the numerator, 49-1 is equivalent to 48.

48/x+4

-7+4 = -3

48/-3

= -16

Solve for x: 5x+3+8x-4=90
aleksley [76]

Answer:

x = 7

Step-by-step explanation:

We can solve the equation 5x+3+8x-4=90 by isolating the variable x on one side. To do this, we must simplify the equation.

5x+3+8x-4=90

Combine like terms:

13x - 1 = 90

Add 1 to both sides:

13x = 91

Divide both sides by 13:

x = 7

Hope this helped!

The volume of a rectangular prism is (x3 – 3x2 5x – 3), and the area of its base is (x2 – 2). If the volume of a rectangular pri
34kurt

To solve the problem we will put the values given to us in the formula of volume of a prism.

<h2>Prism</h2>

A prism is a 3d shape whose two sides are the base sides which are polygon, with the other faces as parallelograms.

The height of the prism is \dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}.

<h2>Explanation</h2>

Given to us

  • volume of a rectangular prism = (x3 – 3x2 5x – 3),
  • area of its base = (x2 – 2)
  • the volume of a rectangular prism is the product of its base area and height,

As given  to us,

\rm{ Volume\ of\ prism = Area\ of\ base \times Height

\rm{ Height=\dfrac{Volume\ of\ prism}{Area\ of\ base}

Substituting the values we get,

\rm{ Height=\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}

Hence, the height of the prism is \dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}.
