You study as much of the times tables as possible and once you have that information stored in your Brain, you use mental math. You can write it down on paper but that’s pretty time consuming if you go at a slow pace.

The volumes of two similar square pyramids is 128 and 250 meters respectively. The side length of the smaller pyramid is 8 meter
Yuliya22 [10]

Answer:

Height of bigger square pyramid = 3.072 meter

Step-by-step explanation:

Using equivalent ratios to find the side of the bigger square prism

128:8 = 250:X

X = (250 x 8) ÷ 128 = 15.625

Volume of a square pyramid = a x a x h/3

Hence to evaluate the height

250 = 15.625 x 15.625 x h/3

H = 3.072 meters

Divide the polynomials:<br> x^2-3x+9/x-2
Kruka [31]

The value of dividing x^2-3x+9 by x-2 is x + 3

<h3>Ways of dividing polynomials</h3>

There are several ways to divide polynomial functions; some of these ways include

  • By factorization
  • By long division
  • By synthetic division
  • By using technology such as graph

<h3>How to divide the polynomials?</h3>

The expression for the polynomial division is given as:

x^2-3x+9/x-2

To divide polynomial functions, we make use of the division by factorization method

Start by expanding the numerator of the polynomial division

x^2-3x+9/x-2 = x^2 + 3x - 6x + 9/x-2

Factorize the equation

x^2-3x+9/x-2 = x(x + 3) - 2(x + 3)/x - 2

Factor out x + 3 from the numerator

x^2-3x+9/x-2 = (x- 2)(x + 3)/x - 2

Cancel out the common factors

x^2-3x+9/x-2 = x + 3

Hence, the value of dividing x^2-3x+9 by x-2 is x + 3
