Answer: x = 17.5

Step-by-step explanation:

All expressions for the angles as a whole must equal 180 because it is on a line.

so we need to set all the expressions equal to 180 then solve.

4x+2x+30+2x+10=180

combine like terms

(4x+2x+2x) + (30+10) =180

8x + 40 = 180

now subtract 40 from each side

8x=140

isolate the x by dividing each side by 8

x = 17.5

What is the coefficient of the x9y-term in the binomial expansion of (2y 4x3)4?

Sonbull [250]

The binomial expansion: $T_{k+1}= \frac{n!}{(n-k+1 )!}a^{n-k} b^{k}$
a = 2y, b = 4 x^3, n = 4
( x )^3k = x^ 9
k = 3
$T_{4}= \frac{24}{6}(2y) ^{3-1} (4x^{3} )^{3}$
$T4=512 x^{9} y$
Answer: the coefficient is 512.
