Answer:
7 meters by 5 meters, or vice versa
Step-by-step explanation:
p = 24 meters
a = 35 meters²
Formula for perimeter = l + l + w + w
Formula for area = l · w
7 and 5 are the only values where the rules are satisfied.
x + x + y + y = 24
7 + 7 + 5 + 5 = 24
14 + 10 = 24
x · y = 35
7 · 5 = 35
Answer:
Minimum: x<-1
Maximum: x> 1
both are also equal to i just don’t have the sign
Answer:
It will 26 weeks to save for the cruise starting from a balance of $140
(It will take 30 weeks in total, if you start saving from $0)
Step-by-step explanation:
let x = number of weeks
Given starting balance = $140
⇒ 140 + 35x = 1050
⇒ 35x = 1050 - 140
⇒ 35x = 910
⇒ x = 910 ÷ 35
⇒ x = 26
