Only C and D are in scientific notation because the decimal has to be after the 3.
Counting how many places you move the decimal to get it behind the 3 we get 8. This is the exponent.
3.0 x 10^8
Answer:63 will be you answer this is how i got it so that is a right traingal wich equals 90 so 90-15-12=63 and you could do 90-12-15=63

Step-by-step explanation:
<h2>GIVEN:-</h2>
The Perimeter of Equilateral triangle = 60cm
<h2>UNDERSTANDING THE CONCEPT:-</h2>
According to the question,
To find the height of the triangle,
Perimeter of Equilateral triangle = Area of Equilateral triangle.
<h2>FORMULA USED:-</h2>
<h2>REQUIRED ANSWER:-</h2>
<h3>SO, The Exact height of the triangle is 120√3cm.</h3>
Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.
Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
