Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
1.
Rate of change: 1:5
Equation: x · 5 = y
Is this relationship proportional? Yes
How do you know? I know, because the table never doesn't follow the equation.
2.
Rate of change: 1:1
Equation: x · 1 = y
Is this relationship proportional? Yes
How do you know? I know, because the table never doesn't follow the equation.
Answer: 37.5
Step-by-step explanation: just multiply! hope this helps!
The ABE and DBC are both made of DBE and and ABD or EBC so if the firsts are equal than these are also equal
