You have the following expression:
8x + 4 + 8x - 1
8x, 4, 8x, and -1 are each terms, and are being added together. Think of each term as an individual box or package. The "boxes" with no variable (in this case, x), which are 4 and -1, can be added normally, but CANNOT be added to the "boxes" with variables. The ones with variables in them are added normally, but CANNOT be added to "boxes" without variables.
Using this information, we know that:
4 + (-1) = 3
and
8x + 8x = 16x (think of 8 + 8 = 16, but labeled with variables)
We can say that the numbers are being added together, but we can't actually add them together. So we can say:
16x + 3
but we can't say:
19x
or
19
So, the answer is:
16x + 3

If d the number of dogs which variable expression represent the phrase below?
To represent the phrase "the number of dogs" as a variable expression, you can simply use the variable ( d ). In this case, ( d ) stands for the total count of dogs being referred to. If you need to express a specific quantity or perform calculations, you can manipulate this variable accordingly, such as ( d + 2 ) for two additional dogs.
If d the number of dogswhich variable expression represnts the phrase below The sum of the number of dogs and the 6 cats?
The variable expression that represents the phrase "the sum of the number of dogs and the 6 cats" is ( d + 6 ), where ( d ) is the number of dogs. This expression adds the number of dogs to the fixed number of cats, which is 6.
Which algebraic expression is equivalent to the expression below (8 times 12) plus 8?
There is no variable in (8x12)+8, so it would be called an arithmetic expression. It would evaluate to 96+8 = 104.
What which choices are equivalent to the expression below Check all that apply. 6(x plus 3) - 5x?
To simplify the expression ( 6(x + 3) - 5x ), first distribute the 6: ( 6x + 18 - 5x ). Combining like terms gives ( (6x - 5x) + 18 = x + 18 ). Therefore, the expression is equivalent to ( x + 18 ). Any choices that simplify to ( x + 18 ) would be equivalent.
If p the number of plant which variable expression represents the pharse below the number of plants divided among 8 yards?
The variable expression that represents the phrase "the number of plants divided among 8 yards" is ( \frac{p}{8} ), where ( p ) is the total number of plants. This expression indicates that the total number of plants is being evenly distributed across 8 yards.
Which choice is equivalent to the expression below 25x - 4x plus 2 x?
To simplify the expression (25x - 4x + 2x), first combine the like terms. Start by adding (-4x) and (2x): (-4x + 2x = -2x). Then, add that to (25x): (25x - 2x = 23x). Therefore, the expression is equivalent to (23x).
What is this expression as an algebraic expression?
The answer is given below:
Which choice is equivalent to the expression below when x 0?
It seems there might be a typo in your question, as "x 0" is unclear. If you meant to ask for a choice equivalent to a specific expression involving ( x ), please provide that expression for an accurate response. If you're looking for a general method to find equivalent expressions, you can simplify the expression using algebraic techniques, factoring, or applying mathematical identities.
