For the equation to be equal it should have a slope of -3
a is part of the equation of the second line.b. <span>is</span> not part because x-3y=-3 -3y=-x-3 y= 1/3x+1 so it is not part of <span>the</span> equation of the second line<span>c</span> is part because y= -3x-6
d. <span>is</span> part because 6x+2y=2 2y=-6x+2 y= (-6x+2<span>)</span>/2 y=-3x+1
So <span>yor</span> answer is B.

Answer:
The correct option is;
C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2
Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame
Hi there!
First, let's find the proportion of the radius' and set it equal to the proportion of the heights:
12/10 = 30/25
Next, we'll cross multiply. If the numbers are the same, then the solids are similar.
300 = 300
The solids are similar! The scale factor from the larger solid to the smaller solid is 6/5 or 1.2. The scale factor from the smaller solid to the larger solid is 5/6.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
