Answer:
f
Step-by-step explanation:
Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19

Hey there!
Here, The equations are:
y = x+1........(i)
4x + y = 6........(ii).
Now,
Putting equation (i) in (ii)
4x + y = 6
4x + (x + 1) = 6
5x + 1 = 6
5x = 6-1
Therefore, x= 1
Putting the value of x in equation (i).
y = x+1
y = 1+1
Therefore the value of y is 2.
<u>Check</u><u>:</u>
y = x+1
2 = 1+1
2=2 ( True ).
