4√10 • 3√ 15
A. 60√6 or
B. 5√6
Which one?

A. 60√6

Step-by-step explanation:

√10 * √ 15 = √ 150

√ 150 = 5√ 6

4 * 3 = 12

12 * 5 = 60

The answer is 60√ 6

x=12 units bd= 10 units

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
