The correct answer is 3x+90=180

Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180

Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30

Study the expression x-y+ z(x + y) Evaluate the expression if x = 10, y = -1, and z=0

Answer:

The value of the expression is 11

Step-by-step explanation:

Evaluate Expressions

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:

$x-y+ z(x + y)$

for x=10, y=-1, z=0

Substituting the variables for their values:

$10-(-1)+ (0)(10 -1)$

$=10+1+ (0)(9)$

$=11+0=11$

The value of the expression is 11
