Answer:
okay ans is A(w)=w2+5w-1/8piw2
First, simplify out the brackets:
-20 - 4n = -12
Then, combine like terms by moving the -20 to the other side
-4n = -12 + 20
-4n = 8
Divide by -4 on both sides to isolate the n
n = 8/-4
n = -2
X = y + 3
2x + y = 9
Solution..
---------------
Substitute for x=y+3 in the second equation...
2x+y = 9
2(y+3)+y=9
2y+6+y=9
3y+6=9
3y=9-6
3y=3
y=3/3
y=1....
Substitute for y=1 in the first equation...
x=y+3
x = 1+3
x=4..
Am sure the answer is quite evident now...
Answer:
7 1/4 yards or 7.25 yards
Step-by-step explanation:
3+3=6
5/8+5/8=1 1/4 or 1.25
6+1 1/4=7 1/4 or 7.25
