A number
, where
are distinct prime numbers, has
divisors.
We know that
has 7 divisors. 7 is a prime number, so among the numbers
there is only one that is equal to 7.
So,
That means
where
is a prime number.
, therefore the
has
divisors.
Divide 20 by 3 to see how much she would wax in 1/5 of an hour.
20/3= 6.66666667
6.66666667 * 5 =
33.3333333

Answer:
multiply the length by the height and the height times 4
Answer:
the sume of two numbers is 2. if one number is subtracted from the other, their difference is 8. find the numbers---->
Step-by-step explanation:
X+Y=2
X-Y=8
If you subtract X+Y with X-Y, you get 2y, and so that equals 2-8, that is -6.
2y=-6
y=(-6)/2
y=-3
-3+X=2
x=2+3
x=5 and y=-8
Check
-3+5=2
5-(-3)=8
Answer:
Area=32 square inches
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the rectangle</em>
Width=w
Length=2×w=2 w
<em>Step 2: Determine the perimeter of the rectangle</em>
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=24 inches
W=w
L=2 w
replacing;
2(w+2 w)=24
2(3 w)=24
6 w=24
w=24/6=4
The width of the rectangle=4 inches
The length of the rectangle=2×4=8 inches
<em>Step 3: Determine the Area of the rectangle</em>
Area=length×width
where;
length=8 inches
width=4 inches
Area=8×4=32 square inches
