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:
12/15 or 4/5
Step-by-step explanation:
4+1+7=12
All three fractions have common denominator which is 15
Answer:
See below
Step-by-step explanation:
Start by subtracting 5.2 from both sides of the equation
so "subtraction property of equality " I suppose ......
then the next step would be divide both sides by 2.5
which would be division property of equality
Answer:
C
Step-by-step explanation:
you need to start by plugging in -2x+4 every were it says y then solve for x when you have found x plug it into one of the equations and solve for y
