Answer:
6
Step-by-step explanation:
if there are five rectangles per scarf and 2/5 are purple than 2/5 of 5 is 2.....this makes 2 rectangles per scarf so 2 times the three scarves equals 6 total rectangles that will be purple.
Answer:
See below.
Step-by-step explanation:
Let the side have a length x units .
The triangle formed by an altitude is a 30-69-90 triangle so the sides are in the ratio 2:1:√3 where √3 is the altitude. Therefore if the side of the triangle = x then altitude = √3 * x / 2 = √3x/2.
So we need to prove that 3x^2 = 4 (√3x/2)^2.
Simplifying:-
4 (√3x/2)^2 = 4 *( 3x^2/ 4) = 3x^2. This completes the proof,
Usaully if you add a larger number with a smaller negative number you will get your answer is 8 + -4+4
