Sorry I am late, but I think the first answer is wrong.

Answer:

53.34

Step-by-step explanation:

42 x .18 = 7.56

42 x .09 = 3.78

---------------------------

7.56 + 3.78 = 11.34

---------------------------

42 + 11.34 = 53.34

---------------------------

Answer = 53.34

Find the values of m &n .. please help !!
matrenka [14]

Answer:

m = 12.728 or 18/root (2)/2, n = 9

Step-by-step explanation:

To find m, we can use sin(45) and cos(45).

Since sin(45) = root (2)/2  and this equals 9/m.

We set the equation root (2)/2  = 9/m and solve for m.

9 divided by root (2)/2 would give us 18/root (2), or 12.728.

m is 12.728.

Same process for n but we are using cosine this time.

cos(45) = root (2)/2 and this equals n/12.728.

Solving for n would give us root (2)/2 times 12.728.

This gives us that n is 9.

Which is the completely factored form of 3xsquared<br> -12x-15?
tekilochka [14]

Answer:

3(x - 5)(x + 1).

Step-by-step explanation:

3x^2 - 12x - 15

Dividing through by 3:

= 3(x^2 - 4x - 5)

We need 2 numbers whose sum is -4 and whose product = -5. That is -5 and +1 , so the factors are:

3(x - 5)(x + 1).

PLEASE PLEASE HELP. I will make you brainlest.
zvonat [6]

Answer: 15 √ 2

Step-by-step explanation:

Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.

You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3

10√6 / 2 * √ 3 = 15 √ 2

The decimal form: 21.2
