Answer:
Step-by-step explanation:
Start by factoring out a -1...
Now, we have to find two integers that multiply to get -16 and have a sum of 6:
(-2)*8=-16
-2+8=8-2=6
Using this, we can split 6x into -2x and 8x...
Factor the first and second half separately...
![f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\](https://tex.z-dn.net/?f=f%28x%29%3D-%5B%28x%5E2-2x%29%2B%288x-16%29%5D%5C%5Cf%28x%29%3D-%5Bx%28x-2%29%2B8%28x-2%29%5D%5C%5C)
Since both x and 8 are being multiplied by x-2, we can combine them to get...

The sum of the exterior angles of a polygon is 360°
The angles were given in terms of x.
We add all and equate to 360° to obtain.
This implies that,

An expression is defined as a set of numbers, variables, and mathematical operations. The value of (3√x + 7), when the value of x is 25 is 22.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The value of (3√x + 7), when the value of x is 25 is,
3√x + 7
= 3√25 + 7
= 3(5) + 7
= 22
Hence, The value of (3√x + 7), when the value of x is 25 is 22.
