Answer:
12 m
Step-by-step explanation:
perimeter is all of the sides together, so 2 7's and 2 x's. You would subtract 14 from 38 to get 24, then divide it by 2 to get the missing side, which is 12
Answer:
(x - 2)(x² + 2x + 4)
Step-by-step explanation:
A difference of cubes factors in general as
• a³ - b³ = (a - b)(a² + ab + b² )
note 8 = 2³ = 8 ⇒ b = 2 , with a = x
Hence
x³ - 8
= x³ - 2³
= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
3 rolls of steamer + 2 packages of balloons = $10 -------------- (1)
2 rolls of steamer + 1 package of balloons = $6.25 --------- (2)
(2) x 2:
4 rolls of steamer + 2 package of balloons = $12.50 --------- (2a)
(2a) - (1):
1 roll of steamer = $2.50 ----------- Sub into (1)
3 ($2.50) + 2 packages of balloons = $10
$7.50 + 2 packages of balloons = $10
2 packages of balloons = $10 - $7.50
2 packages of balloons = $2.50
1 packages of balloons = $1.25
1 packages of balloons = $1.25
1 roll of steamer = $2.50
1 packages of balloons + 1 roll of steamer = $1.25 + $2.50 = $3.75
Answer:
an = -6n + 5.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -1 and common difference d = -6
an = a1 + d(n-1)
an = -1 + -6(n - 1)
an = -1 -6n + 6
an = -6n + 5.
