Here triangles LRU and LAU are congruent

So side RU=AU

3m+21=6m

subtracting 3m from both sides

21=6m-3m

3m=21

dividing both sides by 3

m=21/3 = 7

Answer is A. m=7

Evalute the experssion -280+12x=
Alina [70]
The answer is 23 1/3. First, you need to add 280 to both sides of the equations in order cancel out 280 and get 12x by itself. But remember whatever you do to one side of an equation, you must to do the other. So now you have 12x=280. Now divide both sides of the equation by 12 in order to get x completely isolated. 280 divided by twelve is 23 1/3.

Which of the following is the rational exponent expression of third root of 4 n? A) (4n)3
zhuklara [117]

You have to check which of the following expressions is the rational exponent expression of third root of 4n, or mathematically, \sqrt[3]{4n} . Consider all cases:

A. (4n)^3=4^3\cdot n^3=64n^3\neq\sqrt[3]{4n} .

B. 3n^4\neq \sqrt[3]{4n} .

C. quantity of 4n to the one third power is (4n)^{\frac{1}{3} }=\sqrt[3]{4n} (by the definition of rational power).

D. 4 times n to the one third power is 4\cdot n^{\frac{1}{3} }=4\sqrt[3]{n}\neq \sqrt[3]{4n} .

Answer: correct choice is C.
