Answer:
The perimeter is 220 , the area should be 100 ,
Step-by-step explanation:The perimeter of the square is 40 because it’s all sides added together & they are all even - The perimeter of a circle is always 360 and this is half of a circle so that is a perimeter of 180; you add that to 40=220. The area is two sides multiplied together=100 for the square. You find the area of the half circle by doing the area of a circle divided by 2.
Answer: £36
Step-by-step explanation:
4 Euros = £3
48 Euros (4x12) = £36 (3x12)
You can obviously skip over all the prime numbers. Take 4, 6, 8, 9, 10, 12, 14, etc.
4 only has two proper divisors: 1, 2
sum = 3
6 has three: 1, 2, 3
sum = 6
8 also has three: 1, 2, 4
sum = 7
10 has three: 1, 2, 5
sum = 8
12 has five: 1, 2, 3, 4, 6
sum = 16
12 is the least abundant integer.

Hope this helps.
ANSWER

EXPLANATION
The given equations are:

and

If we add equation (2) to equation (1) we get,

This implies that,.

Divide both sides by 2 to get,

We put x=-1 into equation 1 to get,

We solve for t to get,

This implies that,
