Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum
Vaselesa [24]

Answer:

Step-by-step explanation:

x+y = 175

y = 175 - x

f(x) = (x+3)(y+4)

= x(175-x) + 3(175-x) + 4x + 12

= 175x - x² + 525 - 3x + 4x + 12

= -x² +176x + 537

f'(x) = -2x + 176

maximum when x = 88

y = 175-x = 87

Example<br>2 (3x+11)=10​
Bumek [7]

Answer:

x = -2

Step-by-step explanation:

2 (3x+11)=10​

Divide each side by 2

2/2 (3x+11)=10​/2

3x+11 = 5

Subtract 11 from each side

3x+11-11 = 5-11

3x = -6

Divide each side by 3

3x/3 = -6/3

x = -2
