Answer:
B. 271 square units
Step-by-step explanation:
The area is the sum of 3 rectangles areas
step 1 12 * 19 = 228
step 2 3 * 3 = 9
step 3 2 * 17 = 34
Now, we add all the answers we got to get the area.
= 228 + 34 + 9 = 271 square units
Answer:
x^2 + 18x + 81 complete's the square.
Step-by-step explanation:
y = [x^2 + 18x + (18/2)^2 ] - (18/2)^2
y = [x^2 + 18x + 81] - 81
y = (x + 9)^2 - 81 This is just to make the completion of the square accurate.
You can't just add something to an expression. You have to balance it out.
Well, that would be $0.17 per crayon with tax. The answer with out tax depends on where they were bought. Tax where I live would be 7%, making the crayons' shelf price $19.60, that would be $0.15 per crayon.
<h3>
By Euler's Formula </h3>
F + V = E + 2
<h2>
<u>Solution</u></h2>
<h3>Substuting the values</h3>
⇨ 9 + 14 = E + 2
⇨ 23 = E + 2
⇨ 23 - 2 = E
⇨ 21 = E
Hence , the number of edges in polyhedron is 21.
Y = 1/4x....slope here is 1/4. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, " flip " the number and change the sign. So the negative reciprocal for our perpendicular line is -4.
y = mx + b
slope(m) = -4
(2,-5)...x = 2 and y = -5
now we sub and find b, the y int
-5 = -4(2) + b
-5 = -8 + b
-5 + 8 = b
3 = b
so ur perpendicular equation is : y = -4x + 3
