9cu yd 113 cu in - 4 cu ft 129 cu in

=8 yd³ 22 ft³ 1712 in³

Step-by-step explanation:

To perform the indicated operation we need to convert the given measurements of volume to common units.

1 yd = 3 ft

1 yd³=27ft³

1 ft³=1728 in³

Thus 9 yd³=(27×9)ft³

=243 ft³

113 in³ into ft= 113/1728

9 yd³ 113 in³= 243  113/1728 ft³

4 ft³ 129 in³= 4 129/1728 ft³ = 4 43/576 ft³

Performing the operation given in the equation:

243  113/1728 ft³ - 4 43/576 ft³ = 238  1712/1728 ft³

238 ft³= 8 yd³ 22 ft³ + (1712/1728) × 1728

=8 yd³ 22 ft³ 1712 in³

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
