Question:

2. simplify the following expression.
4(9+ 3x) + (2x2 - 1) – 15 – (2x + 6) + x2

Answers

1. B. 10x-40
2 i think you wrote it wrong but I'm going to guess to the best of my abilities
D. -6

1.
[tex](7x + y) - (5x + 2y) \\ = (7x - 5x) + (y + 2y) \\ = 2x + 3y[/tex]
The value of B is 3

2 .
[tex](8x + 5y) - (2x - 3y) \\ = (8x - 2x) + (5x - 3y) \\ = 6x + 2y[/tex]
The value of B is 2

[tex](-5)^{-6}(-5)^9[/tex]

[tex]= (-5)^{-6+9}[/tex]

[tex]= (-5)^{3}[/tex]

[tex](4 \times 10^{10})(9 \times 10^{-6})[/tex]

[tex]= 36 \times 10^{10-6}[/tex]

[tex]= 36 \times 10^{4}[/tex]

When you simplify it you get that. Hope this helped :)

1) 80

2) 432, -15552

3) 2.734 * 10^7

4)

Step-by-step explanation:

ok, so if we follow the order of operations rules we're told to solve the equation in parentheses first in your case that means we'll be solving (7+3) first

and if you count up 3 from seven you land at 10 simplifying your expression so it now looks like this:

[(10)• 5 -4]÷2+2

now, we can simplify the problem again by doing the next part which is 5-4( because its still in brackets making your problem look like this: (10• 1)÷2+2 or just 10÷2+2

still following the order of operations rule,you must next divide 10 and 2

10÷2=5

and then our problem is 5+2 which is equal to 7!

i really do hope this you, you're welcome in advance! : )
