Answer:

Step-by-step explanation:

Hey There!

To solve this problem we have to combine like terms

$7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2$

So our answer would be

$x^3-2x^2+5x-2$ (b)

A circle with radius 5 has a sector with a central angle of 9/10 pi

Solnce55 [7]

Answer:

35.33

Step-by-step explanation:

The circle with radius 5 has a sector with a central angle of 9/10 pi.

The area of a sector is given as:

$A_s = \frac{\alpha }{2\pi} * \pi r^2$

where α = central angle of the sector in radians

r = radius of the circle

The area of the sector is therefore:

$A_s = \frac{\frac{9 \pi}{10} }{2 \pi} * (3.14 * 5^2)\\ \\A_s = \frac{9}{20} * 78.5\\\\A_s = 35.33$

The area of the sector is 35.33.

Solve for x: x - 10 = -12

andre [41]

Answer:

x = -2

Step-by-step explanation:

Step 1: Add 10 to both sides.

$x - 10 + 10 = -12 + 10$
$x = -2$

Step 2: Check if solution is correct.

$-2 - 10 = -12$
$-12=-12$

Therefore, x = -2.
