The polynomial 6x2 + 37x – 60 represents an integer. which expressions represent integer factors of 6x2 + 37x – 60 for all values of x?

3x – 4 and 2x + 15
3x + 4 and 2x – 15
2(x – 2) and 3(x + 5)
2(x + 2) and 3(x – 5)

Step-by-step explanation:

Given the quadratic polynomial

we have to find the integral factors of the above polynomial.

By splitting middle-term, the polynomial can be written as

Taking 2x common from first two terms and 15 from last two terms.

Taking (3x-4) common

which are required factors of given polynomial.

Hence, option 1 is correct.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

its c or d   take a lucky guess my dude
