-400=-6(8 - 8x) - 4x

Mathematics
1 answer:
Leya [2.2K]3 years ago
4 0

<u>Answer: </u>

The solution of -400 = -6(8 - 8x) - 4x is -8

<u>Solution: </u>

From question, the equation given is,

-400 = -6(8 - 8x) - 4x

Multiplying the terms inside the bracket with -6

-400 = -48 + 48x - 4x

On solving,

-400 = -48 + 44x

In the above equation, move -48 from right side to left side,

-400 + 48 = 44x

Now,

-352 = 44x

44x = -352

Now, the ‘x’ becomes,

x = \frac{-352}{44}

Thus, the value of the variable ‘x’ is:

x = -8

What are the first five terms of the sequence an= n +8?
vladimir2022 [97]

Answer:

9, 10, 11, 12, and 13

Step-by-step explanation:

The first term is determined when n=1, therefore a(1)=1+8=9

The second term is determined when n=2, therefore a(2)=2+8=10

The third term is determined when n=3, therefore a(3)=3+8=11

The fourth term is determined when n=4, therefore a(4)=4+8=12

The fifth term is determined when n=5, therefore a(5)=5+8=13

What is the answer. Please dont send me ‘links’. I seriously need help.
Agata [3.3K]

<u>Answer:</u>

Total Volume of composite figure = 635.2 cm³

<u>Steps:</u>

  • 1.

CV = h×3.14×(d/2)²

CV = 5×3.14(8/2)²

CV = 5×3.14(4)²

CV = 5×3.14×16

CV = 5×50.24

CV = 251.2 cm³

  • 2.

RV = h×w×l

RV = 4×8×12

RV = 4×96

RV = 384 cm³

  • 3.

TV = CV + RV

TV = 251.2 + 384

TV = 635.2 cm³

In the expansion of
Mumz [18]

By the binomial theorem, the x^2 term in the expansion of \left(1-\frac x4\right)^n is

\dbinom n21^{n-2}\left(-\dfracx4\right)^2=\dfrac{n!}{2!(n-2)!}\dfrac{x^2}{16}

which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,

\dfrac{n!}{2!(n-2)!}=\dfrac{n(n-1)}2=21\implies n=7
