To multiply decimals: Set up and multiply the numbers as you do with whole numbers. Count the total number of decimal places in both of the factors. Place the decimal point in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
Answer:
B
Step-by-step explanation:
B
the vertex is (-5,-2) which eliminates A and C. D says that the x intercepts are both positive which is obviously incorrect making B the correct answer
The four angles inside EVERY four-sided figure add up to 360 degrees, no matter what the shape of the figure is.
"Four obtuse angles" means "four angles of more than 90 degrees each".
(four times more-than-90) = more than 360
so NO 4-sided figure can have four obtuse angles inside it.
Answer: 2(n + 4) (n - 4)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula,
a^2 - b^2 = ( a + b ) ( a + b )

Answer:
D B E C A
Step-by-step explanation:
The volume of a rectangular prism (cuboid) can be figured from its dimensions, or from the base area and height:
V = LWH . . . . . volume is the product of length, width, height
V = Bh . . . . . . . volume is the product of base area and height
__
Hopefully, you recognize that these are basically the same formula, since the base area is the product of length and width.
For the given figures, the volumes are ...
A = (1/2 m)(1/4 m)(1/4 m) = 1/32m³
B = (32 m²)(7.25 m) = 232 m³
C = (1/2 m)(1/2 m)(1/4 m) = 1/16 m³
D = (3 1/2 m)(8 1/2 m)(9 3/4 m) = 290 1/16 m³
E = (26 1/3 m²)(5 m) = 131 2/3 m³
__
The volumes from greatest to least are ...
D B E C A
