1. 4 • (–3) • 5
so 4 x (-3) = -12 and then -12 x 5 = -60
2. (2.25 x 23) x 4
so (2.25 x 23) 51.75 and then 51.75 x4 = 207
4. 5 x 12 x (-2)
so 5 x 12 = 60 and then 60 x (-2) = -120
5. 35(26)(0) =
so 35 x 26 = 910 and then 910 x 0 = 0

I first used substitution to get my answer and then used graphing to check. You can easily get a graphing equation by rearranging the second equation.<span />
Answer:
A. a=25
B. RCA and QBD
C. Angle PBA
Step-by-step explanation:
2a-9+5a+14=180 since they are same side interior they equal 180
combine like terms- 7a+5=180
subtract 5 from each side- 7a=175
divide 7 from each side- a=25
