If the following amounts of lumber need to be delivered to each of 2 different staging areas at 4 different job sites, how many total boards of each size will you need?
A. (65) 2 x 45
O (520) 2 x 45
O (500) 2 x 4s
O (540) 2 x 4s
O (580) 2 x 45

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
