The answer is 620. you can use a calculator for these types of questions
4/5 because if you divide it would be 12/15 so I simplified
Answer:
D
Step-by-step explanation:
If you plot both points on a graph you can see the angle is much larger than 58 degrees so it must be 122 degrees. The square root of 13 is less than 4, and you can see that the two points are further than four units apart. Sorry for a non-mathematical explanation, this is just how I solve these things lol.
Answer:
5
Step-by-step explanation:
3+5=8
ANSWER
x=11
EXPLANATION
We want to solve the equation:

Add -8 to both sides:

Square both sides of the equation to get:


Rewrite in the form ax² +bx+c=0


Factor to get,

This implies that,

Checking for extraneous solutions.
When x=6, the original equation becomes,


2+8= 6 is not true.
x=6 is an extraneous solution.
When x=11, the original equation becomes,



This is true, hence x=11 is the only solution.
