Answer:
Its C
Step-by-step explanation:
Okay so you are basically just moving the triangle down two Right? So I believe you are only going to be changing your x axis which is the first out of the two numbers. So your gonna think of it as subtracting 2 from the x axis numbers. Examples, (1,2) you would change that to (-1,2). Or (3,3) that would change to (1,3). Or (4,1) that would change to (2,1). If you do not understand than think of it as money. like if you have 1 dollar but owed two dollars than you would have to owe 1 dollar and Etc
<u>Answer:</u>
- 31 mm² is the surface area.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Surface area of triangle = 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5)
<u>Work:</u>
- 3(1/2 x 4 x 4) + (1/2 x 4 x 3.5) mm²
- => 3(2 x 4) + (2 x 3.5) mm²
- => 24 + 7 mm²
- => 31 mm²
Hence, <u>31 mm² is the surface area.</u>
Hoped this helped.
Multiply the entire equation by the least common denominator which would be 10 to satisfy the the 1/2 and 1/ 5 so
15 = 15x - 12x
15 = 3x
Divide by 3 on both sides
5 = x
