PLEASE HELP ASAP simplify this expression
(Square root 2+square root 3)(square root 5- square root 7)

A. Square root 5+square root -2

B. Square root 20*square root 15- square root 14- square root 21

C.2 square root 5-2sqaure root 7

D. 2 sqrt 5+3 sqrt 5-2 sqrt7-3 sqrt7

its B 10+15-14-21

Step-by-step explanation:

its not hard to simpmy this problem wont explain to much to type

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

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
