Answer: 7
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You know that a multiplication has the following form:
a*b=c
Where a and b are the factors and c is the product.
2. You know one of the factor, then you can find the second one as following:
12*b=84
b=84/12
b=7
Therefore the answer is 7.
Answer:
C is true also
Step-by-step explanation:
The factorization of the expression 36x⁴y³ - 16x³y is 4x³y(9xy² - 4)
<h3>Factorization</h3>
Factorization or factoring is defined as the breaking or decomposition of an entity (for example a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together give the original number. Factorization of an algebraic expression means writing the given expression as a product of its factors. These factors can be numbers, variables, or an algebraic expression.
To the factor, a number means to break it up into numbers that can be multiplied to get the original number.
In the given expression, 36x⁴y³ - 16x³y can be factorized as
36x⁴y³ - 16x³y = 4x³y(9xy² - 4)
The common factor in the expression is 4x³y
