To check whether the statements are correct, we need to convert cm to mm.
surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a
1 cm = 10 mm
7 cm = 70 mm
Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²
<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>

Answer:
The piecewise functions accurately represents charges based on Ben's cell phone plan is :

Step-by-step explanation:
Let x be the minutes over cell phone
Let f(x) represents the piecewise function that represents the charges based on Ben's cell phone plan.
We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.
So,
We are also given that For any minutes over 200, Ben is charged $0.35 per minute.
So, Minutes over 200 = x-200

Hence the piecewise functions accurately represents charges based on Ben's cell phone plan is :

Answer:
Step-by-step explanation:
Let x = base measurement; then height = (x-4).
A = ½•base•height 48 = ½x(x-4
