Use distributive law to factor the given expression: 3+21a+15b

Reil [10]

Answer:

$3(1+7a+5b)$

Step-by-step explanation:

The distributive law states that

$a\cdot (b+c)=a\cdot b+a\cdot c.$

The expression 3+21a+15b consists of three terms:

3=3·1;
21a=3·7a;
15b=3·5b.

You can see that 3 is the common factor of these three terms, thus

$3+21a+15b=3(1+7a+5b).$

In triangle abc, m of acb = 90, cd is perpendicular to ab , m of acd is 60. and bd is 5 cm. find ad

weeeeeb [17]

Let us draw a picture to make the things more clear.

Attached is the image.

We have been given that

$\angle acd = 60 ^{\circ}$

Therefore, we have

$\angle dcb =90- 60= 30 ^{\circ}$

Now, in triangle bcd, we have

$\tan30 = \frac{5}{cd}\\
\\
\frac{1}{\sqrt 3}=\frac{5}{cd}\\
\\
cd=5\sqrt 3$

Now, in triangle acb, we have

$tan 60 = \frac{ad}{5\sqrt3} \\
\\
\sqrt 3= \frac{ad}{5\sqrt3}\\
\\
ad= 5\sqrt3 \times \sqrt 3\\
\\
ad= 5\times 3\\
\\
ad=15$

Thus, ad is 15 cm.
