Answer:

m<1 = 105°

Step-by-step explanation:

<6 and <2 are corresponding angles. Therefore:

m<2 = m<6

Since m<6 = 75°, therefore, m<2 = 75°.

m<1 + m<2 = 180° (linear pair angles)

m<1 = 180° - m<2 (substitution property of equality)

m<1 = 180° - 75° (substitution)

m<1 = 105°

Coefficient of x^2 in expansion of the binomial theorem (2x-1)^4 show your work
tekilochka [14]

Answer:

24

Step-by-step explanation:

If you use Pascal's triangle, which I did, you will look at the 5th row of the triangle which contains the numbers 1, 4, 6, 4, 1

If we expand using a = 2x and b = -1, then the expansion looks like this:

1(2x)^4(-1)^0+4(2x)^3(-1)^1+6(2x)^2(-1)^2+4(2x)^1(-1)^3+1(2x)^0(-1)^4

If you simplify all that down by multiplying, you'll get

16x^4-32x^3+24x^2-8x+1

If you don't know how to use Pascal's triangle, you need to learn.  It's so very cool!

Step-by-step explanation:

21C+15A=945

6C+6A=330

we find adult tickets 1st

42C+30A=1890

42C+42A=2310

12A=420

A=35

we will find children ticket next

42c+30a=1890

30c+30a=1650

12c=240

C=20
