What is the seventh term of (x + 4)8?

Arisa [49]

The (p+1)-th term of the Newton binomial expansion

$(a+b)^{n}$

is given by

$t_{p+1}=\dbinom{n}{p}\,a^{n-p}\,b^{p}$
__________________________

We want the 7th term. Hence, we set $p+1$ to be $7:$

$p+1=7~~\Rightarrow~~p=6$

Then, the 7th term is

$t_{7}=\dbinom{8}{6}\,x^{8-6}\,4^{6}\\\\\\ t_{7}=\dfrac{8!}{6!\cdot (8-6)!}\cdot x^{8-6}\cdot 4^{6}\\\\\\ t_{7}=\dfrac{8\cdot 7\cdot \diagup\!\!\!\! 6!}{\diagup\!\!\!\! 6!\cdot 2!}\cdot x^{2}\cdot 4^{6}\\\\\\ t_{7}=\dfrac{8\cdot 7}{2\cdot 1}\cdot x^{2}\cdot 4^{6}\\\\\\ t_{7}=28\cdot x^{2}\cdot 4,096\\\\ \boxed{\begin{array}{c} t_{7}=114,688\,x^{2} \end{array}}$

Correct answer: $\text{A. }114,688\,x^{2}.$

Step-by-step explanation:

$2(x + 4) = 28$

PLEASE ANWSER CORRECTLY!! I WILL MARK BRAINIEST!!!

Answer:

$x = 10°$

$z = 66°$

Step-by-step explanation:

$(9x - 24)° + (12x - 6)° = 180°\\21x° - 30° = 180° \\ 21 x° = 180° + 30° \\ 21x° = 210° \\ x° = \frac{180°}{30°} \\ x° = 10°$

z° = 9x - 24 ( vertically opposite )

z° = 9(10) - 24

z° = 90 - 24

z° = 66°
