Evaluate the expression 17P2?
To "evaluate" an expression, you need to know the value for the variables.
How do you write an algebraic expression?
Say you had the letter X and you had to times it by 3 then add two the algebraic expression would look like this: 3X + 2 You sometimes need to remember bidmas which helps you remember which part of the sum you do 1st B racets I ndicies D ivision M ultiplication A ddition S ubtractraction Division and multiplication can go the other way around and that's the same as addition and subtraction. If you have to change the algebraic expression back it would be like this 5(x+y) _____ that would be X + Y x 5 / 7 7
What is the algebric expression for 2n 4?
If you mean 2n+4, or 2n-4, that already is an algebraic expression. The idea might be to put it into words. 2n+4 is twice n, increased by 4. Notice you need a comma because if you write twice n increased by 4 this is 2(n+4)
Factor each expression 24AB?
I need to; factor each expression 10x + 40 = ?
How do you solve algabraic expressions?
Expressions are just expressions. Art is an expression and no one can "solve" art. You need problems to solve. In algebra, you'll most likely be looking for equations to solve. Generally you are looking for a simple way to express a variable or to equate the variable to a number. This can be done using what are called "algebraic manipulations". Usually this involves just adding, subtracting, multiplying or dividing each side of an equation (an expression need not have "sides"), however there are many, many different operations than these. wow does that suck....the answer is Elmo
What does it you to evaluate an algebraic expression?
To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]
Evaluate the expression 17P2?
To "evaluate" an expression, you need to know the value for the variables.
How algebraic expression is a difference with two terms?
An algebraic expression need not be a difference of two terms.
How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
How do you get the constant in algebraic expression?
By itself you cannot. You need to have a set of values for the variables and the expression which you need to solve.
How do you write an algebraic expression for the sum of a number and -6 is 4?
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
Why you need convert a expression into postfix expression?
You convert an (infix) expression into a postfix expression as part of the process of generating code to evaluate that expression.
What is value of an expression?
When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
Does an algebraic expression need an answer and equal sign?
It may need an answer but only equations include an equality sign
What is the algebraic expression that describes the height y if x is the width?
Need more context
Why is it important to use order of operations to evaluate algebraic expressions?
I think it is important because you need to know it when you get older.
How do you change algebraic expression into mathematical phrase?
first of all you need to simplify it in the form of a+b
