What is the variable expression of z plus 8?
The variable expression of "z plus 8" is represented as z + 8. In algebra, variables like z can take on different values, while constants like 8 remain the same. When you see "z + 8" in an equation or expression, it means that the variable z is being added to the constant 8.
What phrase describes the variable expression z plus 8?
36
What is the word phrase for this algebraic expression z-23?
Twenty three fewer than a variable represented by z.
How do you factor z squared plus 7z plus 6?
The procedure for factoring z2+7z+6 is as follows: First, we must look at the number in front of the first variable. In this case, it is a 1. Then we look at the last number in the expression, which is a 6 (the expression must be arranged in descending order by the exponents of the variables). Now, we multiply these two numbers together. 1 x 6 = 6 We need to factors of 6 that when added together equal 7. The factors of 6 are as follows 1 x 6 2 x 3 The first set of factors is the only set that adds up to equal 7. So now we break apart the middle term into 1 and 6, so that it looks like this: z2+z+6z+6 Now we group the expression like this (z2+z)+(6z+6) With the parenthesis like this, we can begin pulling out common factors, leaving the expression looking like this z(z+1)+6(z+1) Because the contents of the sets of parenthesis are the same, we can combine the z and the 6 to get the fully-factored expression (z+6)(z+1)
Find an algebraic expression for the quotient of 3 and sum of z and 5?
The algebraic expression for the quotient of 3 and the sum of z and 5 is 3 / (z + 5). In this expression, the numerator is 3, and the denominator is the sum of z and 5. This expression represents dividing 3 by the sum of z and 5.
