What is the value of 46 - 2 × 4 + 7

45

Step-by-step explanation:

46-2 times 4 plus 7

first you do pemdas so u multuply 2 and 4 and get 8 then you do 46 minus 8 then after that you get 38 so then you take 7 and add that to 38 and you end up with 45

45

Step-by-step explanation:

First when solving equations, you have to use PEMDAS, the order of operations

Parenthesis, exponents, multiplication, division, addition, and subtraction

So first you do 2*4=8

Then going left to right

46 - 8 + 7 = ?

46 - 8 = 38

38 + 7 = 45

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
