Answer:
2 is -1/3
3 is -6
4 is 2
Step-by-step explanation:
2 is 7x + 8x = 3x - 4
3 is 5x + (-3) = 2x + (-15)
4 is -4x + 17 = 6x -3
Answer: C = - 71/3 or -23.6 or -23 2/3 All the same
Step-by-step explanation:
Answer:
r=1/π
Step-by-step explanation:
Area of the circle is defined as:
Area = πr²
Derivating both sides
=2πr
=
x
= 2πr
If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have :
=2
Therefore,
2πr
= 2 
r=1/π
Answer: The calculations are done below.
Step-by-step explanation: We are given to find the values for each of the following :
(A) 3 times 5 in 
We know that

Therefore, we get

(B) 3 times 5 in 
We know that

Therefore, we get

(C) 3 times 5 in 
We know that

Therefore, we get

(D) 5 times 3 in 
We know that

Therefore, we get

Thus, the required values are evaluated.
