Step-by-step explanation:
Do FOIL, first outside inside last
3x × 3x = 9x^2
3x × -7 = -21x
7 × 3x = 21x
7 × -7 = -49
So it would just be 9x^2 - 49
Question 1.).
Column A.):
Answer ==> z = 61 – 18, is Related to z + 18 = 61, ==> z = 43
Answer: ===> 18 = 61 - z, is Related to z + 18 = 61, ===> z = 43
z + 18 = 61
Let's solve your equation step-by-step.
z + 18 = 61
Step 1: Subtract 18 from both sides.
z + 18 − 18 = 61 − 18
z = 43
Graph: ========> z + 18 = 61 =========> z =======> 43
Column (A), Answer: =======> z = 43
Question 2.).
Column. B.):
Answer: =====> 61 + 18 = z, Related to z - 18 = 61 ====> z = 79 Answer: ===> –18 = 61 – z, Related to z - 18 = 61 ====> z = 79
z - 18 = 61
Let's solve your equation step-by-step.
z − 18 = 61
Step 1: Add 18 to both sides.
z − 18 + 18 = 61 + 18
z = 79
Answer z = 79
Therefore, The answers to your Equation: Column (A),/Column (B)
