RideAnS [48]

Answer:

The newspaper has 500 readers.

Step-by-step explanation:

We have that:

10 people is 2$ of all newspapers readers, which total t. This means that:

0.02t = 10

t = \frac{10}{0.02}

t = \frac{1000}{2}

t = 500

The newspaper has 500 readers.

The product of two consecutive integers is equal to 14 more than 4 times the sum. This can be simplified to x²-7x-18=0. What are
WITCHER [35]

Answer:

-1 and -2, or 9 and 10

Step-by-step explanation:

If x is the smaller integer:

x (x + 1) = 14 + 4 (x + x + 1)

x² + x = 14 + 4 (2x + 1)

x² + x = 14 + 8x + 4

x² − 7x − 18 = 0

Factor using AC method:

(x − 9) (x + 2) = 0

x = -2 or 9

x is the smaller integer, so the larger integers are -1 and 10.  Check each pair of solutions.

-1 and -2:

(-2) (-1) = 14 + 4 (-2 + -1)

2 = 14 + 4 (-3)

2 = 2

9 and 10:

(9) (10) = 14 + 4 (9 + 10)

90 = 14 + 4 (19)

90 = 90

Both solutions work.

64 + 225 = 289

c^2 = 289

c = Square root of 278

c = 17
