Answer:
As the model is shown below.
As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.
The value of fifth part of each of them is 1/5.
If we consider each part of a thing as one,
So, total number of parts = 15
Total thing=3
So, the answer of the above model is 3÷ 15.
Out of all the options which are 15÷15 , 3÷115 , 3÷15, 15÷15 →3÷15 is correct.
5(z-4)-z=4z-20
5z-20-z=4z-20
4z=4z
z=z
The answer is C
Area of the base = pi*(4x+2)^2 = pi*(16x^2 +16x +4)
volume of cylinder = pi*r^2 *h
V = pi *(16x^2 +16x +4)(5x+4) = pi*(80x^3 +80x^2 +20x +64x^2 +64x +16) =
= pi*(80x^3 +144x^2 +84x +16)
than we consider it without pi so result choice A. is right sure
hope helped
Answer:
2sqrt(10)
Step-by-step explanation:
Use the Pythagorean theorem.
x^2 + 3^2 = 7^2
x^2 + 9 = 49
x^2 = 40
x = sqrt(40)
x = 2sqrt(10)
Answer:
There is no problem to factor.
