Lets say that the length of a rectangle is 12 cm and the width is 5 cm, you would add 12+12+5+5 (as in the length on both length sides and the width on both sides) so the perimeter of this rectangle is: 34 cm
Order of operations
5/8 = 0.625
1/4 = 0.25
0.25*2 = 0.5
0.625-0.5 = 0.125
so the final answer is 0.125
Answer:
(25x2 + 4y2) (5x + 2y) (−5x + 2y)
Step-by-step explanation:
Factor 16y4−625x4
−625x4 + 16y4
=(25x2 + 4y2) (5x + 2y) (−5x + 2y)
There are a number of ways this can be done. One that is fairly simple is as follows.
Triangle ABC has base AC = 9 and height B to AC of 3 (found by counting squares). Thus its area is ∆ABC = (1/2)·9·3 = 13.5 square units.
Triangle ACF has base AC = 9 and height F to AC of 3, so will have the same area as triangle ABC, 13.5 square units.
Trapezoid CDEF has base CD of 6, base EF of 4 and height EF to CD of 6 (found by counting squares). Thus its area is CDEF = (1/2)(6 + 4)(6) = 30.
The total area of the entire figure is then
... ∆ABC + ∆ACF + CDEF = 13.5 + 13.5 + 30 = 57 square units.
