Step-by-step explanation:
The factoring of the difference of squares is ...
r² -s² = (r -s)(r +s)
___
1) (1.2 -a^6b^6)(1.2+a^6b^6) . . . . . . . . r = 1.2, s = a^6b^6
2) (0.9p^3m^2 -0.1x)(0.9p^3m^2 +0.1x) . . . . . . . r = .9p^3m^2, s = 0.1x
Answer:
Step-by-step explanation:
For a rectangular prism, a plane intersecting this prism produces a two dimensional figure as its cross section and in this case the cross section is a rectangle.
For a triangular prism, a plane intersecting this prism produces a two dimensional figure as its cross section and in this case the cross section is a triangle.
Answer:
You can do this two ways
1. Divide 170 into 4 parts and multiply by 3.
170/4=42.5
42.5 x 3 = 127.5 so 127.5 is the answer
2. 3/4=0.75
170 x 0.75 = 127.5
or 170/1 x 3/4 = 510/4 = 127 1/2
127 1/2 = 127.5 because 1 divided by 2 is 0.5__127 + 0.5 = 127.5
