I believe it’s false I’m not too sure I haven’t done that in a while
Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
x=-11
we know that
Points A,B,C,and D are collinear and positioned in that order
so
AD=AB+BC+CD -----> by addition segment postulate
we have
AB=2x+30
AD=x=32
substitute the given values and solve for x
x+32 = (2x+43)
Group terms that contain the same variable
2x-x=32-43
x=-11
