Find the greatest common factor: 12ab^2c^4 + 20a^4bc^3 + 16a^3b

nordsb [41]

Option A

The greatest common factor is 4ab

Solution:

Given that,

We have to find the greatest common factor

$12ab^2c^4+20a^4bc^3+16a^3b$

First find the GCF of numbers

GCF of 12, 20, 16

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

Now find the GCF of variables

$ab^2c^4\\\\a^4bc^3\\\\a^3b$

Here,

ab is the greatest common factor

Therefore, GCF of variables is ab

Thus, GCF of given expression is: 4ab

How is Addy 4+ -4 similar to adding 4+4 how is it different use the words and models to explain

Margarita [4]

4- (+) (-4) is similar to 4+4 by the rule of addition in integers that is if Negative + Negative then Add the number and put the sign of greater number.

<h3>What is integer?</h3>

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers. An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, and 3,043. 1.43, 1 3/4, 3.14, and other numbers that are not integers are some examples. Three categories of integers exist: Zero (0) (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers).

The rules of addition in integers says,

- + - = +

by this,

4-(-4)=8

by concept of addition,

4+4=8

Evaluate the function below for f(3) f (x) = 3x2 - 5 what’s the answer

Novay_Z [31]

The answer is 13 because you would plug in 3(3) which is 9 then you multiply (9)(2) which is 18 they you subtract 18-5 which equals 13
