Step-by-step explanation:
Answer:17
Step-by-step explanation:Follow pemdas.
Start with parentheses which is (5+2) which gives you 7.
Now next in Pemdas is Exponents. SO do 2 to power of 2 which is 4 .Then do 3 to the power of 3 which is 27.Next add 4 to 27 which is 31.so now do 7 times 2 is 14.Then take 31 and subtarct it from 14 which gives you 17.
Look at pic to see clearly how it was solved and the steps. I color code it to show the steps.
First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
Answer: 4.5x + 2
Explanation:
Sum of length and width = (3x-1)+(1.5x+3)
= 3x - 1 + 1.5x + 3
= 4.5x + 2
