Calculate and simplify:

-2+3(1-4)-2​

-17

Step-by-step explanation:

-2 + 3×1 and 3+-4-2

-2 +3-13-2

-4-13

-17

= -2-9-2

= -13

multiply positive 3 into the bracket then add the bases and keep the negative sign

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
