A) 2L + 2W = 48
B) L * W = 140
B) W = 140 / L
Inputting this to equation A)
A) 2L + 2*(140 /L) = 48
L + 140/L = 24
Multiplying both sides by "L"
L² + 140 = 24L
L² -24L +140 = 0
(L -10) * (L-14) = 0
L= 10
L = 14
If length = 10 then width =14
If length = 14 then width = 10
Answer:
5
Step-by-step explanation:

A) 40
B) 30
C) 20
a) 10 and 4
b) 10 and 6
c) 10 and 8
Answers:
C) 20 —-> a) 10 and 4
B) 30 —-> b) 10 and 6
A) 40 —-> c) 10 and 8
Explanation:
20: 10 x 2 = 20 ; 4 x 5 = 20
30: 10 x 3 = 30 ; 6 x 5 = 30
40: 10 x 4 = 40 ; 8 x 5 = 40
Answer:
8x-5y=-20
Step-by-step explanation:
First you have to collect it like terms (5y-8x=20
Then reorder the terms (-8x+5y=20)
Next is to change the signs (8x-5y=-20)
Then you have your answer
