Let's set the measure of each angle equal to 540 degrees.

4x + 4x + 5x + 2 + 96 + 5x - 8 = 540

Combine like terms.

18x + 90 = 540

Subtract 90 from both sides.

18x = 450

Divide both sides by 18

x = 25

Wirte a decimal for each of the following 9x100+2x10+3x0.1+7x0.001

borishaifa [10]

We need to perform multiplication and addition property for this problem to represent the final result in decimal form. So, the expression is,

9x100+2x10+3x0.1+7x0.001 .

Now 9 x 100= 900

2 x= 10= 20

3x0.1= 0.3

7x 0.001=0.007

Now we can all the numbers. Hence,

900+20+0.3+0.007=920.307

So, the decimal number is 930.307.

Step-by-step explanation:

Given

$-2x(x + 3) - (x+1)(x - 2)$

Required

Solve

Open brackets

$-2x^2 -6x - (x^2-2x + x - 2)$

$-2x^2 -6x - x^2-2x + x + 2$

Collect like terms

$- x^2-2x^2 -6x -2x + x + 2$

$-3x^2 -7x + 2$
