Simplify the expression: 2√  20  −   3√  7  −   2√  5  +   4√  63  .           a. 2√  20  −   3√  7  −   2√  5  +   4√  63    b. 2√  20  −   3√  7  +   4√  63    c. 2√  5  +   9√  7    d. 2√  20  −   4√  7  −   2√  5  plz

2 sqrt20 - 3 sqrt7 - 2sqrt5 +4 sqrt63

= 4 sqrt5 - 3 sqrt7 - 2 sqrt5 + 12 sqrt7

= 2 sqrt 5 + 9 sqrt 7

Its C

2√20 - 3√7 - 2√5 + 4√63

4√5 - 3√7 - 2√5 + 12√7

2√5 + 9√7

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
