Answer: tanks of gas
Step-by-step explanation:
Let the x be the number of tanks of gas, then
The amount of gas used by first car=
The amount of gas used by second car=
The amount of gas used by third car=
Thus, the total change in the amount of gas for all three cars=
Since, the amount of gas tanks of gas is used for all three cars.
Therefore, the total amount would be negative .
hence, the answer is tanks of gas.
we know that
The volume of a pyramid is equal to
in this problem
Substitute in the formula above
therefore
the answer is
The volume of the pyramid is equal to
9514 1404 393
Answer:
382 square units
Step-by-step explanation:
The central four rectangles down the middle of the net are 9 units wide, and alternate between 8 and 7 units high. Then the area of those four rectangles is ...
9(8+7+8+7) = 270 . . . square units
The rectangles making up the two left and right "wings" of the net are 8 units high and 7 units wide, so have a total area of ...
2×(8)(7) = 112 . . . square units
Then the area of the figure computed from the net is ...
270 +112 = 382 . . . square units

<em>Additional comment</em>
You can reject the first two answer choices immediately, because they are odd. Each face will have an area that is the product of integers, so will be an integer. There are two faces of each size, so <em>the total area of this figure must be an even number</em>.
You may recognize that the dimensions are 8, 8+1, 8-1. Then the area is roughly that of a cube with dimensions of 8: 6×8² = 384. If you use these values (8, 8+1, 8-1) in the area formula, you find the area is actually 384-2 = 382. That area formula is A = 2(LW +H(L+W)).
I would use long division
Ifthe roots are r1 and r2
then the factored form is
a(x-r1)(x-r2)
so
and multpilcty is how many times the root repeats
P(x)=(x-0)^4(x-2)^3(x-(-1))^2
so the roots are 0 multipilcty 4, 2 mupliticty 3, -1 multplity 2
