Answer:
The greatest number is 18.
Step-by-step explanation:
consecutive: following one after the other
48 ÷ 3 = 16
16 would be the middle number
14 : 16 : 18
14 = smallest number
16 = middle number
18 = biggest number
14 + 16 + 18 = 48
A = L * W
A = 70
70 = L * W
P = 2(L + W)
P = 34
34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L
70 = L * W
L = 17 - W
70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0
W - 10 = 0 L = 17 - 10
W = 10 L = 7
W - 7 = 0 L = 17 - 7
W = 7 L = 10
so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
Answer:

Step-by-step explanation:

I got x=0 because I simplified both sides of the equation and then isolated the equation
Answer:
65
Step-by-step explanation:
2w+ 2l = 300
2w + 170=300
2w= 130
w=65
