9^2= 9.5^2 + 4^2 - 2 (9.5) (4) (cosR) I'm trying to find out the angle measure of R

1 answer:

5 0

Sorry I can't solve it.

Firstly, the equation is wrong. It is supposed to be 81 ≠ 30.25

Second of all, this is the best I got 81= −76 (cos(r) + 106.25

Answer:

$\boxed{x^4 + x^2 + x}$

Step-by-step explanation:

$\frac{x^5 - x^4 + x^3 -x^2 + x - 1}{x - 1}$

$= \frac{(x - 1)(x^4 + x^2 + x)}{x - 1}$

$= x^4 + x^2 + x$

Happy to help :)

Find the solution to the system of equations.

densk [106]

Answer:

x = -2, y = 2

Step-by-step explanation:

-7x + 7y = 28

7y = 28 + 7x

y = 4 + x ----(1)

-8x+4y=24 -----(2)

sub (1) into (2)

-8x+4(4+x)=24

-8x+16+4x = 24

-8x+4x = 24-16

-4x = 8

x = -2

sub x = -2 into (1)

y=4+(-2) = 2
