Answer:
2(L+W) = 34
L + W = 17
.
L*W = 52
L = 2W+5
2L + 2W = 34
L - 2W = 5
--------------- add
3L = 39
L = 13
Answer: L= 65 cm
W= 12 cm
Step-by-step explanation:
Perimeter of rectangle = 2(l+w)
2(l+w) = 154
l + w = 77
From the question
l = 5+ 5w
So 5 + 5w + w = 77
5+ 6w = 77
6w = 72
w = 12 cm
l = 77-b = 77 - 12
= 65 cm

B
Given
14 + 10y ≥ 3( y + 14) ← distribute
14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )
14 + 7y ≥ 42 ( subtract 14 from both sides )
7y ≥ 28 ( divide both sides by 7 )
y ≥ 4 → B
