Using order of operations, I simplified this down to -24+22a.
I hope this helps, and let me know if you need more explanation!
Explanation:
a) The more like a cube or a ball the figure is, the smaller its surface area.
b) Solids with smaller surface area have nearly the same dimension in every direction.
c) Solids with larger surface area have a very high ratio between the largest dimension and the smallest dimension. The flatter or more string-like the figure is, the larger its area.
Answer:
A
Step-by-step explanation:
The figure has two disjoint pairs of consecutive sides which are congruent.
Thus the figure is a Kite
Using the properties of a Kite
• The diagonals are perpendicular
• The main diagonal diagonal bisects the pair of opposite angles
Hence ∠1 = 90° ( diagonals are perpendicular )
The angle 22° is a bisected angle so the angle below is also 22°
The sum of the 3 angles in a triangle = 180°, hence
∠2 = 180° - (90 + 22)° = 180° - 112° = 68°
The solution is A
18y to the 20th power minus 90y to the fifth power
