Write the equation for the area of a triangle with a height that is 5 more than twice its base using one variable. Please help m
zysi [14]

Answer:

A=b(b+\frac{5}{2} )

Step-by-step explanation:

hey there!!!

we know already that the area of a triangle is given as

A=\frac{1}{2}b *h

where b= base

and h= heigth

Given that the height is 5 times more than twice it base

let h= 2b+5

Now we substitute h=2b+5 in the area of the triangle

A=\frac{1}{2}b * (2b+5)

A= \frac{2b^2}{2} +\frac{5b}{2}

A= b^2+\frac{5b}{2}\\\\A=b(b+\frac{5}{2} )

Will all random samples from a given population have the same mean?
Marat540 [252]

Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among samples.

Whats the answer to this? Please help.
BaLLatris [955]

Answer:

The answer is just 1 and 3.

Step-by-step explanation:

To understand this problem, you must think of what whole numbers actually are.

Whole numbers consist of Positive integers and Zero.

Positive integers include 1, 2, 3, 4, 5, 6, ... etc

Zero is 0

The reason \frac{23}{5} isn't a whole number is because that fraction doesn't reduce any further and does not yield a whole number.
