L=w+4m
A=w*l
A=w(w+4)=45
w^2+4w-45=0
w^2+9w-5w-45=0
w(w+9)-5(w+9)=0
(w+9)(w-5)=0
⇒ w+9=0 or w-5=0
⇒w-5=0
w=5
l=5+4
l=9
Answer:
one point (2,-1) with a slope of -3
the equation is based on Y=mx+c
#before that equation We have to find y-intercept which is C here
✔ Y=mx+c here x=2, y=-1 and m(slope) =-3
so
y=mx+c = -1= -3(2) +c= -1= -6+c
there c=5
# Now we can form the equation since we have solved C
✔Y=mx+c = y= -3x+5
Hmm try 192.5 I think that’s right
Answer:
9c -4d
Step-by-step explanation:
6c − 8d + 3c + 4d
Combine like terms
6c + 3c − 8d +4d
9c -4d
