Answer:
21d(10d-3)
Step-by-step explanation:
21d x 10d = 210d^2
21d x 3 = -63d
so it would be 210d^2 - 63d
Answer:
I just answered the other question you asked. Why did you ask the same question twice? Also, I said the 1st one
Step-by-step explanation:
Step 1: Divide both sides by two.
(As shown where 12x - 6 = 10 becomes halved to become 6x – 3 = 5)
Step 2: Add 3 to both sides.
(The 3 is brought to the other side to add to 5, becoming 8)
Step 3: Multiply both sides by 1/6.
(aka dividing both sides by 6, to get the fraction 8/6 which can be simplified to 4/3.)
