Answer:
logx a + logx b
Step-by-step explanation:
A= Area
l= length
w= width
l= w-3cm
A= l*w
A= 53cm²
53= l*w
(plug in value of length)
53= (w-3)(w)
0=w²-3w+53
Use the quadratic formula:
(in the pictures attached)
w= about 9cml=9-3=

Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
