Use the Pythagorean theorem:

$a^2+(2\sqrt3)^2=(4\sqrt3)^2\\\\a^2+2^2(\sqrt3)^2=4^2(\sqrt3)^2\\\\a^2+4\cdot3=16\cdot3\\\\a^2+12=48\ \ \ \ |-12\\\\a^2=36\to a=\sqrt{36}\\\\\boxed{a=6\to C.}$

Used:

$(a\cdot b)^n=a^n\cdot b^n\\\\(\sqrt{a})^2=a$

How do you decide whether a number is a solution of an inequality

disa [49]

Answer:

We can solve inequalities to find all values of the variable that make the inequality true. The idea is to get the variable all by itself on one side of the inequality sign so we can easily see the solutions to the inequality.

Hence for any given inequality and for any given number if we put that number in that inequality and see that the given inequality sign holds true than that number will be a solution of the inequality otherwise it is not an solution of the inequality.

Which scale factors produce a contraction under a dilation of the original image?

Leokris [45]

Answer:

1/2

-1/2

Step-by-step explanation:

we know that

If a dilation produce a contraction that means that the absolute value of the scaling factor is less than 1

If a dilation produce an enlargement that means that the absolute value of the scaling factor is greater than 1

Verify each case
