Answer:
Width=4, and Length=17
Step-by-step explanation:
first you will make a variable for the width which i will say is x
now make it an equation (3x+5) (x) = 68
then solve 3x^2+5x=68
then 3x^2+5x-68=0
then x=4
then you have to substitute so 3(4)+5= 17 and 4
A 4/6
b 1/3 is equivalent to 2/6 and 3/3 to 6/6 cant think of another one
c to find equivalent fractions just look at the number underneath?
Answer:
First number = 33, Second number = -19
Step-by-step explanation:

Our two equations then are F + S = 14 and 2F + 3S = 9
We can use substitution:
Answer:
-11
Step-by-step explanation:
The number and sign after x is always the y-intercept
638 divided by 11= 58. 58x9=522
