What is another way to express 42 + 24?choices: 8(5+3) 6(7 + 4) 4(10 + 6) 14(3 + 2)

6(7+4) is correct.

Step-by-step explanation:

answer each problem one by one. for the first one, 8(5+3), 8 times 5 is 40. you need 42, not 40. for the second one, 6(7+4), 6 times 7 is 42. 6 times 4 is 24. this problem simplified is 42+24. so that one is correct. but still, study every problem to understand. 4(10+6) is the third problem. 4 times 10 is 40. not correct. 14 times 3 is 42. that is correct so let's see where this problem leads to. 14 times 2 is 28. not correct. therefore, 6(7+4) is correct.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
