Answer:
x=1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
6
Step-by-step explanation:
all you have to do is 30 / 5 what equals 6
Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
<u> *(a+12b) </u>
a²- 12ab
<u> +12ab - 144b² </u>
<u> a² +0 - 144b² </u>
We see we get the same answer as applying the formula above.
F(x)=x/6+2
There is no restriction upon the values of x, or the values of y.
So the domain and range are both the set of all real numbers.
x=(-oo, +oo) and y=(-oo, +oo)
This can be further seen by the fact that this is a line with a slope of 1/6. So there is no restriction upon x as all values of x produce real values of y. And y approaches -oo as x approaches -oo and y approaches +oo as x approaches +oo.
Answer:
480m
Step-by-step explanation:
First we have to find the perimeter of the field.
We know that the area is 144m and that the field is a square.
Since a squares sides are all equal, we can do 
, which is 12m.
So, one side of the field is 12m; now we just find the perimeter which is easy since its a square. 12*4=48m
If Andrea walked around it 10 times, then we just multiply the perimeter by 10
48*10=480m
