1. Factor completely 2x^2 + 9x + 4

2. Factor completely 3x^2 − x − 4

3. Factor completely 18x^2 − 21x −15

4. Factor completely 3x^2 + 5x + 1

5. Factor completely the following:
5a. x^2 − 4x − 12
5b. x^2 + 4x − 12
5c. x^2 − x − 12
5d. x^2 − 7x − 12

6. Given the trinomial, what is the value of the coefficient 'B' in the factored form? (2 points)

2x^2 + 14xy − 36y^2 = 2(x + By)(x − 2y)

B=

i believe that the answer is

b. y-1=-2(x-4)

hope this !

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

answer:

c) the x-coordinate of the center of the circle increases by 3
