The number of scented candles packaged in a box can vary by at most two from an average of 80 candles per box. if the cost of producing a candle is two dollars, what is the range of the possible production costs, x, for 50 boxes of candles?
a. 78 ≤ x ≤ 82
b. 156 ≤ x ≤ 164
c. 3,900 ≤ x ≤ 4,100
d. 7,800 ≤ x ≤ 8,200

Step-by-step explanation:

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
