The maximum happens at x = -b/2a
x = -48/2(-16) = 3/2
Now replace x in the equation and solve for y:
y = 48(3/2) - 16(3/2)^2
y = -72 - 36
y = 36
The maximum height is 36 feet.

The whole house (100%) correspond to the number 1
so
using proportion
Find out how long will it take her to clean the whole house
Answer is 16
35=2x+3
35-3=32
32=2x
32/2=16
Answer:
3 ft at each end
Step-by-step explanation:
The lot area is 7 x 5 = 35ft2
The planned lot area = 143ft2
The plan is to extend the lot by equal length on both the width and the length therefore we can express the extension as y the planned lot can be express as
(5+y) x (7+y) = 143
y2 +12y+ 35 = 143
y2 +12y - 108= 0 expand the equation
y2 +18y - 6y -108= 0 factorise the equation
(y-6) (y+18) = 0
(y-6) =0 or (y +18)= 0
y =6. or y = -18
Length can only be a positive number hence y =6
However we need to note that we are increasing the 4 directions a length has 2 end so increasing at both end implies
6/2 = 3 ft at each end
