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

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 $\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}$ .
