Find the greatest common factor of 12a^3b, 16a^2b^2, and 36ab^3
scoundrel [369]

<u>Answer: </u>

The greatest common factor of 12 a^{3} b, 16 a^{2} b^{2}, 36 a b^{3} \text { is } 4 a b

<u>Solution: </u>

To find the greatest common factor we have to find the prime factors of individual numbers and then find the number which is common to each given number.

Here the numbers are 12 a^{3} b, 16 a^{2} b^{2}, 36 a b^{3}

Let us find out the prime factors of each number .

\begin{array}{l}{\text { Prime factors of } 12 a^{3} b=2 \times 2 \times 3 \times a \times a \times a \times b} \\ {\text { Prime factors of } 16 a^{2} b^{2}=2 \times 2 \times 2 \times 2 \times a \times a \times a \times b \times b} \\ {\text { Prime factors of } 36 a b^{3}=2 \times 2 \times 3 \times 3 \times a \times b \times b \times b}\end{array}

We can see that 2 \times 2 \times \mathrm{a} \times \mathrm{b}  is common to all the given numbers 12 a^{3} b, 16 a^{2} b^{2}, 36 a b^{3}

Therefore the greatest common factor of 12 a^{3} b, 16 a^{2} b^{2}, 36 a b^{3} \text { is } 2 \times 2 \times a \times b=4 a b

HELP PLEASE&lt;3 <br> Find the missing angle <br> Btw its trigonometry
ira [324]

Answer:

x = 16.6

Step-by-step explanation:

Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

tan(\theta) = \frac{opposite}{adjacent} \\tan(31^o)=\frac{10}{x}\\x=\frac{10}{tan(31^o)} \\x \approx 16.64279

which rounded to one decimal is

x = 16.6
