Answer: -1.51, or it could be 4.09 < 5.6 (Im sorry if I get it wrong I just wanted to help)
Step-by-step explanation:
Answer:
a. 6(7) + 2(3)^2 = 60
b. (5(-18)/3)-2 = -32
c. (6(10))^2 - 10/5 = 3598
d. (1-3)(1+2) = -6
Step-by-step explanation:
Answer:
3/7 - 1/12 is equal to 29/84, which is less than 1/2, so no, it is not greater than 1/2.
Let me know if this helps!
Answer:
Im not quite sure the awenser to part 1 but part 2 is yes they are
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
