To represent this as an equation, you need to show both things that are mentioned in the paragraph. 1. You begin at 600 cm. And 2. The tree grows 3.1 cm per week.
You put both of these together in one equation like this: 600 + 3.1w = h, where w stands for the number of weeks and h stands for the height.
So first of all, find d. It is the only letter you can be sure of because all of them are the same. So 3d = 9. Divide by 3 to get d = 3. Now 2C + 3 = 21, because there are 2 C's in the bottom row. Subtract 3 from both sides to get 2C = 18. Divide by 2 to get C = 9. 2C + A = 21, or 18 + A = 21. Subtract 18 from both sides to get A = 3. A + B + C = 14, or 3 + B + 9 = 14. Combine like terms to get 12 + B = 14. Subtract 12 from both sides to get B = 2. So A = 3, B = 2, C = 9, and D = 3.
It’s B

Answer:
Option (4)
Step-by-step explanation:
From the graph attached,
Local minimum → (3, -4)
Global Maximum → (-0.44, -4.3)
Maximum of the function → (1.7, 0.7)
Since, local maximum lies in the interval 2.5 ≤ x ≤ 4
Interval that contains the local minimum will be→ [2.5, 4]
Therefore, Option (4) will be the correct option.
Answer:
<h2><u><em>
20√2</em></u></h2>
Step-by-step explanation:
The diagonal of a square is given as, √2 × side. Rearranging this formula to calculate the side of the square, we get, side = diagonal/√2 = (√2 × diagonal)/2 . Thus, the perimeter of the square can be calculated using the formula, P = 2√2 × diagonal.
Diagonal = 5 * 2 = 10
P = 2√2 * 10
P = 20√2
