Answer:
- 14
Step-by-step explanation:
Substitute n = 4 into the n th term formula, that is
B(4) = 4 - 6(4 - 1) = 4 - 6(3) = 4 - 18 = - 14
among 8 groups. How many unit cubes
will each group get?
A 40
B 44
C 45
D 48
There are 5,280 feet in one mile. How
many feet are there in 6 miles?
A 30,680
B 31,260
C 31,608
D 31,680
6. Alice has 1/5
as many miniature cars as
Sylvester has. Sylvester has 35 miniature
cars. How many miniature cars does
Alice have?
A 7
B 9
C 40
D 175
Each group will get 45 unitcubes.
There are 31,680 feet in 6 miles.
Alice has 7 miniaturecars.
It is a polygon having six faces.
The volume of a cube is side cube.
We have,
To divide the 360 unit cubes equally among 8 groups, we need to perform the division:
= 360 รท 8
= 45
To find out how many feet there are in 6 miles, we need to multiply the number of feet in one mile by 6:
= 6 miles x 5,280 feet/mile
= 31,680 feet
If Sylvester has 35 miniature cars, and Alice has 1/5 as many as Sylvester, we can find the number of miniature cars that Alice has by multiplying Sylvester's number by 1/5:
= 35 x 1/5
= 7
Thus,
Each group will get 45 unitcubes.
There are 31,680 feet in 6 miles.
Alice has 7 miniaturecars.

Using PEMDAS you start with parenthesis
(-3)(5) = -3 x 5 = -15
-15 + 10 = -5
The answer is -5
Answer:
Yes
Step-by-step explanation:
(x-1)(x+1)(x-3i)(x+3i)
FOIL ( x-1) (x+1) = x^2 -x+x-1 = x^2 -1
FOIL (x-3i)(x+3i) = x^2 +3ix -3ix -9i^2 = x^2 -9(-1) = x^2 +9
(x-1)(x+1)(x-3i)(x+3i) = (x^2 -1) (x^2 +9)
FOIL again
x^4 +9x^2 -x^2 -9
x^2 +8x^2 -9
This is the factored form
perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
