Answer:
x= -1.
Step-by-step explanation:
4-2(x+7) = 3(x+5)
4 - 2x-14 = 3x +15
10-2x=3x+15
10=5x+15
-5 = 5x
-1 = x

Answer:
40.8
Step-by-step explanation:
A cube has 6 sides.
A cube is all made up of squares.
So, we need to find the area of one cube and multiply that by 6.
Length * width= area
40*40= 1,600
Multiply that by 6.
1,600*6= 9600
Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.
9,600 (the unit) ^2
I hope this helps!

Answer:
0.153
Step-by-step explanation:
It has been a long time since I've done this, so I hope it is correct:
cos = adjacent side / hypotenuse
cos x = 13 / 85 = 0.153
Point slope form says the line through (a,b) with slope m is
y - b = m(x - a)
Here that's
y - - 1 = -2(x - -4)
Answer: y + 1 = -2(x + 4)
