Answer:
(2x – 7) × (2x + 7)
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = (4x² – 49) m²
Dimension =?
The picture in the question above has a rectangular shape. Thus, the area is given by:
Area (A) = Length (L) × Width (W)
A = L × W
The dimension of the shape will be:
L × W
Now, we shall determine the dimension (L × W) as follow:
Area (A) = (4x² – 49) m²
Dimension (L × W) =?
A = L × W
L × W = 4x² – 49
Recall:
4 = 2²
49 = 7²
Thus,
L × W = 2²x² – 7²
L × W = (2x)² – 7²
Different of two squares
L × W = (2x – 7)(2x + 7)
L × W = (2x – 7) × (2x + 7)
Dimension = (2x – 7) × (2x + 7)
Therefore, the possible dimension (L × W) of the shape is (2x – 7) × (2x + 7)
Answer: There are <u>4</u> teams in the league
Step-by-step explanation:
(1) Add 14 four times: 14+14+14+14 = 56
(2) Multiply 14 four times: 14 x 4 = 56
(3) Combine both of these numbers into the <em>t </em>factor: 14t = 56
(4) Divide both sides by 14 and simplify: (14t / 14) = 56/14 | t = <u>4</u> (simplified)
The answer would be C.
Hope this helps! (:
It would be 115,000. You round down since 16 is closer to 115,000 than 116,000.
