Answer:

Step-by-step explanation:

Given

x² + 8x = 4

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(4)x + 16 = 4 + 16, thus

(x + 4)² = 20 ← equivalent equation

Answer:

100 paws

Step-by-step explanation:

the ratio is 4:1 and you need to know is how many paws there are for 25 tails. if you divide 25 by 1 the answer is 25 and if you multiply 1 by 25 you get 25 and if you multiply 4 by 25 you get 100. (you multiply 4 by 25 because 1 was multiplied by 25 to get the amount of tails)
