The variables x, y, and z represent polynomials where x = a, y = 3a – 5, and z = a2 + 2. what is x2y – z in simplest form?

2a2 – 5a – 2
3a3 – 6a2 – 2
–3a3 – 2
–3a2 – 2

The simplest form of is

Option 2 is correct.

Step-by-step explanation:

Given: The variables X, Y, and Z represent polynomials.

We need to find

Substitute the value of X, Y and Z into expression

Combine the like term

Simplest form is

Hence, The simplest form of is

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
