Answer:
see below (I hope this helps!)
Step-by-step explanation:
41. √20 = √4 * 5 = √4 * √5 = 2√5
43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.
45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x
47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.
Answer:
B 32
Step-by-step explanation:
sqrt(71*x)
71 is prime
sqrt(71) sqrt(x)
A. 19 prime
B. 32 = 16*2 16 is a perfect square
C. 34 = 2*17 both of which are prime
D. 41 prime
sqrt(71) sqrt(16 *2) = sqrt(71) * sqrt(16) * sqrt(2) = sqrt(71)*4*sqrt(2)
=4sqrt(142)
