Take a factor out of the square root:
Allisa [31]

Answer:

Question A)

=\sqrt{6}x

Question B)

=3a\sqrt{a}

Question C)

=5\sqrt{2}b^2

Step-by-step explanation:

A)

We are given:

\sqrt{6x^2}\, \text{ where } x\geq 0

We can rewrite the expression:

=\sqrt{6}\cdot \sqrt{x^2}

The square root and square will cancel each other out. Thus:

=\sqrt{6}x

B)

We are given:

\sqrt{9a^3}

Rewrite:

=\sqrt{9}\cdot \sqrt{a^3}

Note that the square root of 9 is simply 3. We can also factor the second part:

=3\cdot \sqrt{a^2\cdot a}

Rewriting:

=3\cdot\sqrt{a^2}\cdot\sqrt{a}

Simplify:

=3a\sqrt{a}

C)

We are given:

\sqrt{50b^4}

Rewrite. Note that 50 = 25(2):

=\sqrt{25}\cdot \sqrt{2}\cdot \sqrt{b^4}

Simplify. We can rewrite the factor as:

=5\cdot \sqrt{2}\cdot \sqrt{(b^2)^2}

The square and square root will cancel out. Thus:

=5\sqrt{2}b^2

Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.
astraxan [27]

Answer:

-24

Step-by-step explanation:

-  \frac{5}{2} x \:  - 5 = 55

Multiply through by the denominator (that is, 2)

= 2 \times ( -  \frac{5}{2} x) \:  - 5(2) = 55(2)

=  - 5x - 10 = 110

Collect like terms

- 5x \:  = 110 +10

- 5x = 120

Divide through by - 5x

\frac{ - 5x}{ - 5}  =  \frac{120}{ - 5}

x =  - 24

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th
antoniya [11.8K]

Answer:

The answer is 6x^{3} +39x^{2}+54x

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = x+2

Width (w) = 3x

Height (h) = 2x+9

By substituting these values to the equation above,

Volume of the rectangular prism = (x+2)*3x*(2x+9)

                                                      =(3x^{2} +6x)*(2x+9)

                                                      =6x^{3} +27x^{2} +12x^{2} +54x

                                                      =6x^{3} +39x^{2}+54x

Therefore,

The answer is 6x^{3} +39x^{2}+54x
