1 answer:

5 0

$x {}^{2} + 6x - 6 = 10$
$x {}^{2} + 6x - 6 - 10 = 0$
$x {}^{2} + 6x - 16 = 0$
$(x + 8)(x - 2) = 0$
$x = - 8 \: \: and \: \: x = 2$

The volume of the square base pyramid is 588 ft³

The Volume of the rectangular prism is 120 ft³

The Volume of a rectangular pyramid is 360 ft³

<h3>What is volume of a shape?</h3>

Volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.

Volume of a square base pyramid = 1 / 3 × B × h

where

B = base area

Therefore,

Volume of a square base pyramid = 1 / 3 × 7² × 12

Volume of a square base pyramid = 1764 / 3 = 588 ft³

Volume of a rectangular prism = lwh

Volume of a rectangular prism = 6 × 5 × 4 = 120 ft³

Volume of a rectangular pyramid = 1 / 3 lwh

Volume of a rectangular pyramid = 1 / 3 × 10 × 12 × 9 = 1080 / 3 = 360 ft³

What are the answers

Natalka [10]

Answer:

The value of x = 15.75

Step-by-step explanation:

∵ PQ and LM are two chords in the circle and intersected outside the circle at point N

∴ NM × NL = NQ × NP

∵NM = 14 and NL = 14 + 22 = 36

∵ NQ = x and NP = 32

∴ 14 × 36 = x × 32

∴ x = (14 × 36) ÷ 32 = 15.75

If f:R→R is continuous at a point c∈ R and g:R→R is continuous at f(c)∈R, then the composition g(f(x)) :R→R is continuous at c.

natima [27]

Answer:

The assertion that g(f(x)) is continuous at c is true.

Step-by-step explanation:

$let\\a=\lim_{x\rightarrow c}f(x)$

$\because f(x)$ is continuous at c

$\\\\Similarly\\\\b=\lim_{x\rightarrow f(c)}g(x)$

$\because g(x)$ is continuous at $\ x=f(c)$

$\lim_{x\rightarrow c }g(f(x))=g(f(c))\\\\=g(a)$ which is defined as per given data thus g(f(x)) is continuous at x=c

How many solutions are there to the equation below?

skad [1K]

Answer:

A. Infinitely many

Step-by-step explanation:

9x + 27 = 9(x + 2) + 9

Distribute on the right side.

9x + 27 = 9x + 18 + 9

Combine like terms on the right side.

9x + 27 = 9x + 27

Subtract 27 from both sides.

9x = 9x

Divide both sides by 9.

x = x

x = x is a true statement for every value of x. Therefore, any value you substitute in for x will make the original equation true. That means there is a infinite number of solutions.

Answer: A. Infinitely many
