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
Answer:
x=45
Step-by-step explanation:
180-90=90÷2=45
Irrational
i dont know how to explain this one, but its irrational
I was taught that if you must simplify a square root by doing the birthday cake method. Basically divide the radical by its lowest common factor until it can't be divided anymore. Also the lowest factor can't be 1. For 27, the lower common factor is 3.
27/3 = 9/3 = 3
Since in a common square root the index is 2, you must pair the least common factors. There is 1 pair of 3 and there is 1 remaining

is 3

.
You must multiply 3 and 8, which gives 24
The answer is 24
