Answer:56
Step-by-step explanation:
the answer is 56 because when u multiple all of them together the answer is 56
2x2=4
2x7=14
14x4=56
i hope this helps
For a, the answer is 2. for b, the answer is 12
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
c
=
144
.
Explanation:
Divide the coefficient of
x
(not
x
2
) by 2, and then square that.
So for
x
2
−
24
x
, dividing
−
24
by
2
gets us
−
12
.
Squaring
−
12
gets us
144
,
So
c
=
144
.
In general:
Consider the factoring identity
(
x
−
a
)
2
=
x
2
−
2
a
x
+
a
2
If we only have the middle term,
−
2
a
x
, then dividing the middle term by
2
x
gets us
−
2
a
x
2
x
=
−
a
(If we only take the coefficient on
x
, we do not have to divide by
x
.)
Then if we square that, we get
(
−
a
)
2
=
a
2
So as you can see, taking the coefficient on
x
, dividing it by
2
, and then squaring it will get us the magic constant that lets us complete the square.
The value of f(25) and f(-66) are 3 and -4 respectively
<h3>Functions and values</h3>
Given the function below:
![f(x) = \sqrt[3]{x+2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%2B2%7D)
To get the value of f(25), we will substitute x = 25 into the function to have:
![f(25) = \sqrt[3]{25+2}\\f(25) = \sqrt[3]{27}\\f(25) = 3](https://tex.z-dn.net/?f=f%2825%29%20%3D%20%5Csqrt%5B3%5D%7B25%2B2%7D%5C%5Cf%2825%29%20%3D%20%5Csqrt%5B3%5D%7B27%7D%5C%5Cf%2825%29%20%3D%203)
Similarly for f(-66)
![f(-66) = \sqrt[3]{-66+2}\\f(-66) = \sqrt[3]{-66}\\f(-66) = -4](https://tex.z-dn.net/?f=f%28-66%29%20%3D%20%5Csqrt%5B3%5D%7B-66%2B2%7D%5C%5Cf%28-66%29%20%3D%20%5Csqrt%5B3%5D%7B-66%7D%5C%5Cf%28-66%29%20%3D%20-4)
Hence the value of f(25) and f(-66) are 3 and -4 respectively
