Hoi!

Let's add the numbers with variables first.

3w + 2w = 5w

Plug that in

5w - 3x - 6 - 8

Now let's add the terms without variables. 6 is a negative because there's a subtraction symbol in front of it.

-6 - 8 = -14

Now plug that in to get your final answer.

Your simplification is 5w - 14 - 3x.

How do you do number 1?<br>Whenever I tried to answer it, I always get fraction. help me.​
Flura [38]

Answer:

The pairs are (13,15) and (-15,-13).

Step-by-step explanation:

If n is an odd integer, the very next odd integer will be n+2.

n+1 is even (so we aren't using this number)

The sum of the squares of (n) and (n+2) is 394.

This means

(n)^2+(n+2)^2=394

n^2+(n+2)(n+2)=394

n^2+n^2+4n+4=394               since (a+b)(a+b)=a^2+2ab+b^2

Combine like terms:

2n^2+4n+4=394

Subtract 394 on both sides:

2n^2+4n-390=0

Divide both sides by 2:

n^2+2n-195=0

Now we need to find two numbers that multiply to be -195 and add up to be 2.

15 and -13 since 15(-13)=-195 and 15+(-13)=2

So the factored form is

(n+15)(n-13)=0

This means we have n+15=0 and n-13=0 to solve.

n+15=0

Subtract 15 on both sides:

n=-15

n-13=0

Add 13 on both sides:

n=13

So if n=13 , then n+2=15.

If n=-15, then n+2=-13.

Let's check both results

(n,n+2)=(13,15)

13^2+15^2=169+225=394.  So (13,15) looks good!

(n,n+2)=(-15,-13)

(-15)^2+(-13)^2=225+169=394.  So (-15,-13) looks good!

tia_tia [17]

Answer:

(2x-4)^2-9 => 4(x-2)^2-9

Step-by-step explanation:

=> 4x^2-16x+7\\ =>(2x)^2-2*(2x)*(4)+7\\ =>(2x)^2-2*(2x)*(4)+(4)^2-(4)^2+7\\ =>(2x-4)^2-9\\ =>4(x-2)^2-9
