Answer:

Step-by-step explanation:

1) let’s bring all the like terms(terms that have the same variable) together so we can combine them

Bring”6m” to the left(doing this will make 6m negative) And bring 30 to the right(doing this will make 30 negative)

*they switch spots basically*

4m-6m=-30

-2m=-30

Divide both sides by -2

M=15

Hope this helps!

Answer:

M = 15

Step-by-step explanation:

To get m alone you need to subtract 4m by both sides

4m - 4m + 30 = 6m -4m

30 = 2m

Now last part is to divide 2 by both sides

30/2 = 2m/2

M = 15

Which of the following three sets of lengths could be used to form a right triangle A 39,15 and 36

laila [671]

Step-by-step explanation:

To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.

We try out all the options:

39² = 1521, 15² + 36² = 1521.

12² = 144, 8² + 4² = 80.

17² = 289, 13² + 9² = 250.

Since 39² equals 15² + 36², option A is the correct answer.

Answer:

a = 3/2
b = -1/2

Step-by-step explanation:

$\dfrac{\sqrt{5}-1}{\sqrt{5}+1}=\dfrac{(\sqrt{5}-1)(\sqrt{5}-1)}{(\sqrt{5}+1)(\sqrt{5}-1)}\\\\=\dfrac{5-2\sqrt{5}+1}{5-1}=\dfrac{6-2\sqrt{5}}{4}\\\\=\dfrac{3}{2}-\dfrac{1}{2}\sqrt{5}$

Comparing this to the form a+b√5, we see that ...

a = 3/2

b = -1/2
