Answer:
24
Step-by-step explanation:
Let 'x' be the number
x +25% of x = 30
x + 0.25x = 30
1.25x = 30
x = 30/1.25
x = 24
Step-by-step explanation:
The formula for the lateral area of a right cone is :
LA = rs
Where
r is the radius of the base and s is the slant height of the cone
Equivalent expression,
or
Hence, this is the required solution.
The polynomial is: 
Step-by-step explanation:
We need to write a polynomial f(x) that meets the given conditions: Degree 3 polynomial with zeros 3,-5,4
Since zeros are at 3,-5 and 4
So, x=3, x=-5 and x=4
or:
x-3=0, x+5=0 and x-4=0
Multiplying all factors to find the polynomial:
So, the polynomial is:

Answer:
Multiples of 8 are: 8, 16, 24, 32, 40, 48, 56
Step-by-step explanation:
Answer:
length = 20m
width = 16m
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
Firstly, I would assume that you made a unit error for the perimeter, which I would believe is meters.
With that, we can now make these statements:
Perimeter = 72m
Perimeter = 2l + 2w
therefore,
2l + 2w = 72
Since the question states the width is 4 meters less than the length, we can make this statement,
w = l - 4
We can now substitute this into the first statement we made, 2l + 2w = 72
2l + 2(l - 4) = 72
2l + 2l - 8 = 72
4l - 8 = 72
4l = 80
l = 20m
Using the second statement, w = l - 4, we can now find w,
w = 20 - 4
w = 16m
Therefore, the length is 20m and the width is 16m
