Answer:

Angle LMO = 50°

Step-by-step explanation:

1) We need to solve for x.

We know angle LMN = 90°, and that angles LMO and NMO add up to angle LMN. That gives us this equation:

3x + 38 + 10x = 90

Now, we solve for x!

Combine like terms

13x + 38 = 90

Subtract 38 from both sides

13x = 52

Divide both sides by 13

x = 4

Now we know what x is.

2) Plug in x to angle LMO's given value (3x + 38)

3(4) + 38 = angle LMO

12 + 38 = angle LMO

50° = angle LMO

IgorLugansk [536]

Answer:

50%

Step-by-step explanation:

2,000 is 2 x more than 1,000. Or, 1,000 is half of 2,000 and half of 100%=50%.

Evaluate f(x) = 4x + 3x^2 − 5 when x = -2. 23 -1 -25 -49

frozen [14]

Answer:

f(-2) = -1

Step-by-step explanation:

One way of doing this is to substitute -2 for x in every place where x shows up:

f(x) = 4x + 3x^2 − 5 → f(-2) = 4(-2) + 3(-2)^2 − 5

→ f(-2) = -8 + 3(4) - 5, or f(-2) = 4 - 5, or f(-2) = -1

The diagram shows a 5 cm x 5 cm x 5 cm cube.

mylen [45]

Answer:

~8.66cm

Step-by-step explanation:

The length of a diagonal of a rectangular of sides a and b is

$\sqrt{a^2+b^2}$

in a cube, we can start by computing the diagonal of a rectangular side/wall containing A and then the diagonal of the rectangle formed by that diagonal and the edge leading to A. If the cube has sides a, b and c, we infer that the length is:

$\sqrt{\sqrt{a^2+b^2}^2 + c^2} = \sqrt{a^2+b^2+c^2}$

Using this reasoning, we can prove that in a n-dimensional space, the length of the longest diagonal of a hypercube of edge lengths $a_1, a_2, a_3, \ldots, a_n$ is
