Factor completely 10xy + 3y + 20ax + 6a.
(10x − 3)(y − 2a)
(10x − 3)(y + 2a)
(10x + 3)(y + 2a)
(10x + 3)(y − 2a)

Option 3 is correct.

Step-by-step explanation:

The given expression is

This expression can be written as

Take out the common factors from each parenthesis.

Now, take out the common factor (10x+3).

Therefore option 3 is correct.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
