Area of aqua: A = bh/2 = (13.4cm) (4cm)/2 = 26.8cm2
Total area trapezoid: A = (a+b/2)h = ((13.4cm + 18cm)/2) 4cm = 62.8cm2
Area of purple = Total area - area of
aqua = (62.8cm2) - (26.8cm2) = 36cm2
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy
A.a1 is the first term in the sequence
D.n is the index of sequence
is the correct answer....
