Answer: <em>-10x+38</em>
Step-by-step explanation:
<em>Take your given equation</em>
<em>-2(3x-5)+4(7-x)</em>
<em>Distribute the -2 and 4 into the parenthesis'</em>
<em>-6x+10+28-4x</em>
<em>Combine like terms</em>
<em>-10x+38</em>

Idk your best bet is to look it up online thats what i do often
Edward because they completed more days and miles !!
Answer:
The bearing is N 55.62° W
Step-by-step explanation:
ship leaves the port of Miami with a bearing of S80°E and a speed of 15 knots.
It then turns 90° towards the south after one hour.
Still maintain the same speed and direction for two hours.
The bearing is just the angle difference from the ship current location to where it started.
Let the speed be km/h
Distance covered in the first round
= 15*1
= 15km
Distance covered in the second round
=15*2
= 30 km
Angle at C = (90-80)+90
Angle at C = 10+90= 100
Let the distance between the port and the ship be c
C²= a² + b² -2abcos
C²= 15²+30²-2(15)(30)cos 100
C²= 225+900+156.28
C²= 1281.28
C= 35.8 km
Using sine formula
30/sin x= 35.8/sin 100
30/35.8 * sin 100 = sinx
0.838*0.9848= sin x
0.8253= sin x
Sin ^-1 0.8253 = x
55.62° = x
The bearing is N 55.62° W
Answer:
226.19
Step-by-step explanation:
pi * r^2 = area
The radius = diameter/2 = 6
pi * 6^2 * 2 = area of 2 tortillas
72pi = area of 2 tortillas
That rounds to 226.19
