Answer:
<em>The value of the expression is 11</em>
Step-by-step explanation:
<u>Evaluate Expressions</u>
An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.
To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.
Let's consider the expression:
for x=10, y=-1, z=0
Substituting the variables for their values:
The value of the expression is 11
Answer:
Step-by-step explanation:
honestly, there's not really a step by step tutorial, you just pretend like the square root 17 is x and do exactly like you'd do otherwise. -3x-4x= -7x and the x is square root 17 so you just put it together like that <3
Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
