-4(x-7)=36
-4x+28=36
-4x=8
x=-2
2a+b4.....................
2x+4(2x+7)+3(2x+4)
2x+8x+28+6x+12
16x+40
16x+40 would be the answer you can’t solve it any further
B is false, since by the inclusion/exclusion principle,

By independence, we have
, which is zero if either of
or
is 0, which isn't guaranteed.
Answer:
1. 4 is the constant
2. x > -2
3. 2.86 inches
^The formula for the circumference of a circle is C=2∏r, in which r=radius. To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
