Acuboid, with dimensions 28cm by 16cm by 15cm, has a volume of 6720cm cube. the cuboid is melted to form smaller cubes of length 4cm. how many cubes can be obtained?

Aline passes through 3,7 and 6,9 what equation represents the line

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
