This is part 1. Please help

For the first one you would do:
X rad 3=7 divide by rad 3 in both sides and you don’t wanna leave a radical in the denominator so multiply rad 3 in both denom. And numerator and then you get 7rad3/3.

A 30:60:90 triangle always have n:2n:n rad 3 so since 2n=10 you would get n=5 and since BC is n rad3 so you would get 5rad 3.

In a 45:45:90 triangle it is n:n:n rad 2, since AC=3 then AB= 3 and then BC= 3 rad 2

Since AC and AB are congruent you they both would be 12 so it is true.

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen
jolli1 [7]
First, you need to isolate the x in the first equation. 
-x + 5y = 1
Subtract 5y from both sides, leaving you with the following equation: 
-x = 1-5y
Because you are trying to solve for positive x and not negative x, you need to make x positive. Therefore you divide both sides by -1. In Algebra, when 1 is the coefficient of the variable, it is not shown, but it is still there. The new equation will be the following: x = 5y-1
Now you just need to substitute the x within the second equation for the x equation we just solved for. 

Therefore, the right answer will be 2(5y-1)+4y= -4. Now, all you have to do is choose the answer that states exactly that, which is the first choice.

Step-by-step explanation:

x and 6

6^2 is 36

x^2 is still x^2

now we need to find the square root of their sum

square root of ( 36 + x^2 )

I'm not that sure about this one i think it might be more simplified
