Answer: A and B
<u>Step-by-step explanation:</u>
Here is Pascal's Triangle:
Row 1 (x + y)⁰ 1
Row 2 (x + y)¹ 1 1
Row 3 (x + y)² 1 2 1
Row 4 (x + y)³ 1 3 3 1
Row 5 (x + y)⁴ 1 4 6 4 1
∵
Row n (x + y)ⁿ⁻¹ 1 (sum of 2 digits above) 1
C and D are false. A and B are the only correct answers
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
Answer:
z would equal 20°
Step-by-step explanation:
This means ACB and EFD are 2 similar triangles
They have the same shape but different size
In ACB because 3 corner of a traingle must = 180° so in this case, corner BAC would = 180 - 65 - 55 = 60°
As you can see, BC is 3 times as large as DF, this means triangle ACB is larger than triangle EFD 3 times, this would lead to corner BAC is larger than corner DEF 3 times.
Corner DEF would = corner BAC / 3
= 60° / 3
= 20°
SO z would equal 20°
