I’m sorry but the photo is not loading for me so I can’t really help you tho
Answer:
A = -y^2 + 18
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)
Step-by-step explanation:
Given:
P = 2 ( l + w)
x = length and y = width
P = 2 (x + y)
36/2 = x + y
x + y = 18
x = 18 - y
<u>Area:</u>
A = x * y
A = (18 - y) * y
A = 18y - y^2
Using quadratic formula (<u>solve for y</u>):
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)

Answer:
one
Step-by-step explanation:
for general form : ax²+bx+c=0
delta = b²-4ac
so for this example delta is 8²-4×2×8 =0
we know if delta = 0 , we have just one real number solution
so the answer is 1
8
5
8
5
hopefully its right i'm not good at this kind of stiff
Your givens are A+S=326 and 8A+5S=1972.
A+S=326
-S -S
A=326-S
if you substitute this into the other equation that you are given it looks like this
8(326-S)+5S=1972.
After this we use PEMDAS to solve for S
2608-8S+5S=1972
2608-3S=1972
-3S=(-636)
-S=(-212)
S=212
If we know S=212 we can go back and solve the origonal equation for A.
A+212=326
A=114
