The expression is written as (4n/9) + 14
What is an expression?
An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. To assist identify the sequence of operations and other features of logical syntax, mathematical symbols can denote numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. Many writers differentiate between an expression and a formula, with the former referring to a mathematical item and the latter referring to a statement about mathematical things. For instance, is a formula. However, in modern mathematics, and particularly in computer algebra, formulae are considered as expressions that may be evaluated as true or false based on the values assigned to the variables in the expressions.

Answer:
2 pieces
Step-by-step explanation:
Given
Required
Calculate the number of pieces
To do this, we have to divide the length of the wood by the length of each piece.
Represent this with x
Convert mixed numbers to improper fraction
Change division to multiplication
<em></em><em> </em>
The answer is C Becase all rationals are positive so to get the answer make them negative so c is the answer
Answer:
Part A) The scale factor is
The dimensions of the larger rectangular prism are
Part B) The volume of the smaller rectangular prism is
Part C) The volume of the enlarged rectangular prism is
Step-by-step explanation:
Part A)
we know that
If the dimensions of the prism are doubled, then the scale factor is equal to
so
To find the dimensions of the larger rectangular prism, multiply the scale factor by the dimensions of the smaller rectangular prism
Part B) What is the volume of the smaller rectangular prism?
we know that
The volume of a rectangular prism is equal to
we have
substitute the values
Part C) What is the volume of the enlarged rectangular prism?
we know that
The volume of a rectangular prism is equal to
we have
substitute the values
Remember that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z------> scale factor
x-----> volume of the enlarged prism
y-----> volume of the smaller prism
so
we have
substitute
---> is ok
Answer:
D: 13b^3 - 18b^2 - 7b + 12
Step-by-step explanation:
First expand the brackets by multiplying (10b^2+7b-3) by -1
Then rearrange the terms so you can see where you have to add them together.
Then simplify
