Answer:
Step-by-step explanation:
1. Area of a parallelogram = base * height
area = 10 * 4 = 40 in squared
perimeter = 2(a + b)
perimeter = 2 * (5 + 10) = 2 * 15 = 30in
2. Area of triangle = 1/2 * base * height
area = 1/2 * 21 * 8 = 84 cm squared
perimeter = sum of outer perimeters
perimeter= 10cm + 17cm + 21cm = 48cm
3. area of trapezium = 1/2 * (a+b) * h
area = 1/2 * (6+12) * 4 = 36ft squared
perimeter = sum of outer perimeters
perimeter = 5ft + 6ft + 12ft + 5ft = 28ft

Answer:
Well for one. This is the wrong section as its mathematics. I believe this is a science question. That being said. The answer here is the Suns Core.
Explanation:
The suns core has more than 15 million Kelvin and is tightly-packed and dense.
Answer:
15
Step-by-step explanation:
3x - 2y = ?
3(7) - 2(3) = ?
21 - 6 = ?
= 15
All you have to do is substitute the given values & follow the order of operations! Best of luck.
1/3 oranges were spoiled.....u threw away 4 oranges...
1/3 of what = 4....
1/3x = 4
x = 4 * 3
x = 12 oranges
1/4 grapefruits were spoiled....u threw away 7
1/4 of what = 7
1/4x = 7
x = 7 * 4
x = 28
so ur fruit basket contained 12 oranges and 28 grapefruits before u discarded the spoiled ones
