Answer:
B.
w=P-2l/2
Step-by-step explanation:
That is the same thing
1*2*3
Do 8-5 to get 3 then,
do 1*2*3=6
If you had 4! you would do,
1*2*3*4=24
Answer:
8 by 8.
Step-by-step explanation:
A triangular sail to be constructed with a vertical and a horizontal poles for support. The combined weight of the poles cannot exceed 80 pounds and the poles weigh 5 pounds per foot gives us a total length of 80/5=16 feet. Let us call the length of horizontal pole by x and we have (16-x) for the vertical one. We want to maximize area of the sail, so [tex] A(x)= x (16-x)/2 [\tex] is the function we want to maximıze on [0, 16].
Answer:-6y+12
Step-by-step explanation:
(2y+3)×(y-6)=2y^2-9y-18
2y^2-9y-18-2y^2+3y+30
Combine like terms
2y^2-2y^2=0
-9y+3y=-6y
-18+30=12
-6y+12
