Answer:
38 feet
Step-by-step explanation:
P(x) = ℓ(x) + ℓ(x) + w(x) + w(x)
= x + x + (4x - 1) + (4x - 1)
= (x + x + 4x + 4x) + (-1 -1)
= 10x - 2
P(4) = 10(4) -2 = 38
The perimeter is 38 feet when the length is 4 feet long, so Cho will need to
cover 38 feet with garden stones.
Answer:
A
Step-by-step explanation:
Using the definition
n =
where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then evaluating numerator and denominator
10
=
=
Cancel 7(6)(5)(4)(3)(2)(1) on numerator/ denominator, leaving
= =
= 120
-------------------------------------------------------------------------------------
6
=
=
Cancel 4(3)(2)(1) on numerator/ denominator, leaving
=
= 15
-------------------------------------------------------------------------------------
Dividing numerator by denominator gives
= 8 → A
