If x + 4 = 32, does x = 8?

Mathematics

Answer:

Step-by-step explanation:

I say no because if we were to replace x with 8, the equation should look like this = 8 + 4 = 32. Since this doesn't make sense, 8 cannot be x. X would be 28 which would equal 32 and would be the right answer.

Use the unit circle to evaluate the followingHow do I solve this problem?

Ilya [14]

Notice that:

$\cos (\frac{4\pi}{3})=\cos (\pi+\frac{\pi}{3})\text{.}$

Recall that:

$\cos (\pi+x)=-\cos (x)\text{.}$

Therefore:

$\cos (\frac{4\pi}{3})=-\cos (\frac{\pi}{3})=-\frac{1}{2}\text{.}$

Answer:

$cos(\frac{4\pi}{3})=-\frac{1}{2}\text{.}$

How many blocks fill this prism?

zaharov [31]

Answer : 72 blocks

To find the answer, you have to find the volume of the prism. To find the volume you multiply the length, width, and height.

6 x 3 x 4 = 72

This gives you 72 blocks.

What is the angle of DBC

Licemer1 [7]

When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:

3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.

We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86
