Answer:

Volume of square pyramid = 330.24 inches³

Step-by-step explanation:

Question No 20

Base of Square Pyramid = 8 inches

Height of Square Pyramid = 15.5 inches

We need to determine the volume of pyramid.

The formula used is: Volume\:of\:Square\:Pyramid=a^2\times \frac{h}{3}

Putting values of base and height of pyramid and finding volume

Volume\:of\:Square\:Pyramid=a^2\times \frac{h}{3}\\Volume\:of\:Square\:Pyramid=(8)^2\times \frac{15.5}{3}\\Volume\:of\:Square\:Pyramid=64 \times 5.16\\Volume\:of\:Square\:Pyramid=330.24\:inches ^3

So, Volume of square pyramid = 330.24 inches³

Is the answer true or false?
stira [4]

Answer:

The answer to your question is False

Step-by-step explanation:

Original division

                       \frac{3x^{3}+ 5x^{2}- 11}{2x + 1}

Process

1.- To express a division in a synthetic form we must take the coefficients of the numerator. If there is no coefficient for a variable, we write it as 0.

          3x³ + 5x² - 11 =         3    5   0   - 11

The "0" means 0x, this term is not present but we must consider it.

2.- Solve the denominator for x

                 2x + 1 = 0

                 2x = -1

                   x = -1/2

3.- Write the synthetic division

                           -1/2      3    5   0   -11

Which expressions are equivalent to <br> x+x+x+2?
Alexxandr [17]

Answer:

3x + 2

Step-by-step explanation:

x = 1x but leaving the x alone equals the exact thing.

If there are x + x + x, this means 3x since it is also

1x + 1x + 1x.

This is another expression for 3x + 2.

Find all values of $x$ such that $\sqrt{4x^2} - \sqrt{x^2} = 6$.
artcher [175]

For this case we must solve the following equation:

\sqrt {4x ^ 2} - \sqrt {x ^ 2} = 6

To solve we follow the steps below:

We square both sides of the equation squared:

(\sqrt {4x ^ 2} - \sqrt {x ^ 2}) ^ 2 = 6 ^ 2\\(\sqrt {4x ^ 2}) ^ 2-2 (\sqrt {4x ^ 2}) (\sqrt {x ^ 2}) + (\sqrt {x ^ 2}) ^ 2 = 36\\4x ^ 2-2 (\sqrt {4x ^ 2 * x ^ 2}) + x ^ 2 = 36\\4x ^ 2-2 (\sqrt {4x ^ 4}) + x ^ 2 = 36\\4x ^ 2-2 (2x ^ 2) + x ^ 2 = 36\\4x ^ 2-4x ^ 2 + x ^ 2 = 36\\x ^ 2 = 36\\x = \pm \sqrt {36}\\x = \pm6

We choose the positive value because we talk about $. x = 6

Answer:

$6
