Use Pascal's Triangle
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1 (this is the row you use)
So, the seventh term of (3x + 2y)^9 will be 84xy
Answer:
2! Thank it if it was helpful :D
Step-by-step explanation:
7x-4x=3+3
3x=6
x=2
Greater than 20 because 5×6=30 so it passed
Answer:
<u>Option 90°</u>
Step-by-step explanation:
AB is the perpendicular bisector of XY
The result of intersection will give 4 right angles
So,the measure of the angle of intersection when AB is the perpendicular bisector of XY = 90°
See the attached figure.
