Given that f(x) = x + 4 and g(x) = x + 7, find (g - 4(x).
Answers
Answer: The value of \((g - f)(x)=4 .\)
Step-by-step explanation:
Given functions : \(f(x) = x + 4\) and \(g(x) = x + 7\)
To find : \((g - f)(x)\)
Difference between two functions: \((u-v)(x)=u(x)-v(x)\)
Then, \((g-f)(x)=g(x)-f(x)\)
\(=(x+7)-(x+4)=x+7-x-4\\\\=7-4=3\)
Hence, the value of \((g - f)(x)=4 .\)

Subtracting a negative is the same as adding. Example: 2-(-3) = 2+3 = 5.
So (x+y)-(-z) is the same as x+y+z. We can group up terms inside parenthesis and it won't change the result. Meaning that x+y+z is the same as any of the following below

Which shows one way to determine the factors of x3 - 12x7 - 2x + 24 by grouping?
Answers
The factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).
To determine the factors of the polynomial x^3 - 12x^2 - 2x + 24 by grouping, we can follow these steps:
Step 1: Group the terms in pairs. In this case, we can pair the first two terms and the last two terms:
(x^3 - 12x^2) + (-2x + 24)
Step 2: Factor out the greatest common factor from each pair. From the first pair, we can factor out x^2, and from the second pair, we can factor out -2:
x^2(x - 12) - 2(x - 12)
Step 3: Notice that we now have a common binomial factor of (x - 12) in both terms. Factor out this common binomial factor:
(x - 12)(x^2 - 2)
Therefore, the factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).

1. In this isosceles triangle, all the angles are equal. What is the measure of angle xº?
90
120
We need more information to solve
360
Answers
But I’ll try to help you with this problem. Here are two cases.
One, the problem is actually an equilateral triangle and all sides are indeed equal. The angles in a triangle adds up to 180 degrees. So if all angles are equal, divide 180 by 3 and you get 60. So all angles would be 60 degrees and so should x.
Two, the triangle is isosceles, we will cross out the rest of sentence one after the comma. Since there are no given information about the triangle and I believe the random numbers below the question are the choices, I will teach you how to do this problem. It’s easy. So we already know that a triangle adds up to 180, now we will take 180 and subtract it by the two given and known angles. The remaining number will be what x is.

What is meant by Quadrilateral?A quadrilateral is a four-sided polygon with four angles and four vertices.

The outcome of an image The perimeter of the quadrilateral ABCD is 85 feet. Find out what the value of x is.The perimeter of a quadrilateral is the entire length of its boundary. Perimeter = AB + BC + CD + DA, for example, can be used to define the perimeter of the quadrilateral ABCD.The perimeter is 85. (the total of all sides). X = 5.5, and 4x + 3x + 4 + 5x-7 + 6x-11 = 85 (18x - 14 = 85). 18 x = 85 + 14 = 99.Therefore,
The perimeter of ABCD can be calculated using the following formula: Line AB + Line BC + Line CD + Line DA = Perimeter ABCD.
