Well, if the cement block is going to get painted, then you would have to find the surface area of that rectangular solid.
Multiply 4.5 by 7.25 to get the area of one side, then multiply that answer by 2 to get the area of the side opposite the given side. You'd end up with the area for two congruent sides.
Next, multiply 4.5 by 6.5. Multiply the sum by 2, since there is another congruent side opposite that.
Lastly, multiply 6.5 and 7.25, since they are the only numbers left to multiply anyway. Multiply the product by 2.
Your work should look somewhat like this:
4.5 x 7.25 = 32.625 (x2)
4.5 x 6.5 = 29.25 (x2)
6.5 x 7.25 = 47.125 (x2)
32.625 + 29.25 + 47.125 = 109
Multiply 109 by 2 (there are 6 sides to this prism; 3 are listed, so multiply 2 to get the area of the other 3)
FINAL ANSWER: 218 feet squared
Answer:
see below
Step-by-step explanation:
prove: sin²x cos²y - cos²x sin²y ≡ sin²x - sin²y
we notice that the Right side only has sin² functions, hence we can start by trying to remove the cos² functions from the Left side.
Recall the identity: sin²α + cos²α = 1 , can be rearranged to give us:
cos²α = 1 - sin²a.
If we apply this to the left side of our equation, then
cos²y = 1-sin²y, and cos²x = 1-sin²x
Substituting these into the left side of the equation:
sin²x cos²y - cos²x sin²y
= sin²x (1-sin²y) - (1-sin²x ) sin²y
= sin²x - (sin²x sin²y) - sin²y + (sin²x sin²y)
= sin²x - sin²y
= Right Side of equation (Proven!)
1. And the meeting house windows, blank and bare, / Gaze at him with a spectral glare.
This is a <em>couplet</em>. You can tell this because there are two lines, a couple, as indicated by the slash between the phrases, as well as the end words rhyming.
2. A glimmer, and then a gleam of light / He springs to the saddle, the bridle he turns / But lingers and gazes, till full on his sight / A second lamp in the belfry burns.
This excerpt, I believe, is meant to highlight the <em>end rhymes</em>. You see, in the first and third lines, the last words rhyme, and the second and fourth lines' last words rhyme.
3. ...the Mystic meeting...
Seeing as how this is so incredibly short, and both "mystic" and "meeting" start with an "m", it is safe to assume that this is meant to highlight an <em>alliteration</em>. An alliteration is when two or more words in a row start with the same letter. A famous alliteration is in the tongue twister, "she sells seashells by the sea shore."
4. ...like a sentinel's thread / The watchful night wind...
This is a <em>simile</em>. Both similes and metaphors compare one thing to something generally more abstract in order to describe it better. In order to tell if something is a simile or a metaphor is to look for the words "like" or "as," because those are used in similes, but not metaphors. Since this uses the word "like," it is safe to assume that this is a simile.

Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that . 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have . Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
