To find the sum:

Therefore the answer is a^3+12a^2+14a+5.
Hope it helps!
Step-by-step explanation:
Im not sure if its supposed y = -2x + 1 or y = 2x + 1 but I'll solve the problem for both.
First for y = -2x + 1
Since the line has to be parallel to y = -2x + 1
the slopes would be the same.
so, so far the equation would be
y = -2x + b
now we substitute (5,2) into the equation
2 = -2(5) + b
2 = -10 + b (Add 10 to both sides of the equation)
+10 +10
12 = b
Now that we solved for b
The equation would be
y = -2x + 12
^^ This equation is parallel to y = -2x + 1
Now to solve for an equation parallel to y = 2x + 1
Both equations would have the same slope
So far we would have
y = 2x + b
Now we solve for be by substituting the point (5,2)
2 = 2(5) + b
2 = 10 + b (subtract 10 from both sides)
-10 -10
-8 = b
After solving for b
The equation is
y = 2x - 8
This equation is parallel to y = 2x + 1
The first two are 6 and 28. The factors of 6 add up to the same thing as 6.
Six
1 * 2 * 3 = 6
1 + 2 + 3 = 6
Twenty eight
1 + 2 + 4 + 7 + 14 = 28 (the multiplication is not the same as for 6).
Four hundred ninety Six
This one is kind of hard to believe
It is 16 * 31
1 + 2 + 4 + 8 + 16 + 248 + 124 + 62 + 31 = 496
Answer:
L = the slanted height of the pyramid
Step-by-step explanation:
The surface area of a pyramid is given by :

Where
P is perimeter of base of pyramid
L is the slant height of the pyramid
B is the area of base.
So, the correct option is (c) "the slanted height of the pyramid".
Answer:
24.44 percent
Step-by-step explanation:
F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
