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

Let f(x) = -4x + 7
Tema [17]

g(x) = 2x-6

f(x) = -4x +7

(g•f)(x) = g(f(x))

= 2(f(x)) - 6

= 2 ( -4x+7) -6

= -8x + 14 -6

= -8x +8

now

(g•f)(1) = -8(1) + 8= -8+8

= 0

so option a is answer
