Answer:
i think its 7. x² + 11x - 268. x² + 14x - 120
Keep the base and add the powers.
25^(1/2)= 5
Answer:
Step-by-step explanation:
first you solve what's in the parenthesis 10^6=1000000
1000000 * 5 = 5000000
10^8=100000000
times by 3
=300000000
answer is
1500000000000000
Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set 
alone on one side of the equal sign. Your equation will look like 
.
3.) Plug 
in for in the first equation. You will get 
.
4.) Distribute. Your equation now looks like this: 
.
5.) Combine like terms. You will get 
.
6.) Subtract 6 from both sides. You get 
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like 
and the bottom equation would look like 
. We basically got our answer of 
, but we will plug it into the equation, and in-fact, we get x = -3.
