Question

write the algebraic expression modelled by the tiles given below.​

Answer 1

Answer:

The algebraic expression is $-x^{2}+4x-3$

Explanation:

From the question, we have

We will have to first convert the given algebra tiles to the expressions,

$-x^{2} +(x+x+x+x)+(-1-1-1)\\=-x^{2}+4x-3$

Hence, the algebraic expression is $-x^{2}+4x-3$

Algebraic Expressions :

When addition, subtraction, multiplication, division, and other mathematical operations are performed on variables and constants, the result is known as an algebraic expression. Suppose James and Natalie were playing with matchsticks when they had the idea to create number patterns with them. James made the number 4 with four matchsticks. In order to create a pattern with two 4s, Natalie added three extra matchsticks. They understood that they could keep adding three matchsticks each round to make an additional "four" by doing so. They deduced from this that, generally speaking, in order to create a pattern with n number of 4s, you need 4+ 3(n-1) sticks. We refer to 4+ 3(n-1) as an algebraic expression.
