4x^2+23x-72=
4x(x+8)-9(x+8)=
i got dis 4 yo answer and it is (x+8)(4x-9)
hope dis helped
Answer:
(c) Factor
Step-by-step explanation:
The constituents of a product are its factors.
Dividing a product by one of its factors will not leave a remainder.
__
A <em>term</em> is a constant or product of one or more variables and a constant. For example, -4 and 24xy are both <em>terms</em>.
A <em>multiple</em> is a product with one factor being an integer. For example, 3×1.5 = 4.5 is a <em>multiple</em> of 1.5.
A <em>variable</em> is a symbol for an unknown value. Commonly, a variable is a single letter, but may also be a blank (__) or a question mark (?). Sometimes a word or phrase is used as a variable. For example, ...
3 + x = 5
3 + __ = 5
3 + ? = 5
3 + (some number) = 5
38.4 I times 12.80 by 3 .
p.s I use a calculator☺
Answer: 
Step-by-step explanation:
1. You know that the force acting on the object varies directly with the object's acceleration. Then, by definition, you have:

Where
is the force acting on the object,
is the object's acceleration and
is the constant of proportionality.
2. Keeping this on mind, you can calculate the constant of proportionality by substituting
and
into the equation and solving for
:

3. Now, you can calculate the force when the acceleration of the object becomes 5 m/s², as following:

3. The result is:

Answer:
Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
Step-by-step explanation:
The null hypothesis is basically the problem statement i.e
Pulse rates of men have a standard deviation equal to 10 beats per minute
Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
The alternate hypothesis will contradict or negate the null hypothesis i.e
H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
