Divide the polynomials using long division.

Mathematics
1 answer:
Basile [38]3 years ago
3 0

Answer:

1.x+1 with -5 as the remainder. 2.4x+15 with 40 as the remainder. 3.2x-16 with 68 as the remainder.

Step-by-step explanation:

Do the division house thing. put x square plus 4x minus 2 inside. multiply by x and put it on the roof. you will have x square plus 4x minus x square minus 3x. the x squares cancel out. Bring down the -2 and 1x from the subtraction before. u will have 1x-2. multiply by 1 to x-3. the x cancels and -2-3 equals -5. so 5 is the remainder. do the same house, and roof structure. Multiply by 4x...put on roof. the 4x squares cancels out. and 4x times 2 equals 8x. 8x+7x equals 15x. bring down the 10. multiply by 15. the x cancels. then 10+30(from 15x2) equals 40. 40 is the remainder. do the same ti tge third. 2x times x equals 2x square. the 2x squares cancels. multiply 2x by 5. -10x-6x=-16x. bring down the -12. multiply by -16. -16x+16x cancels out. since 16times -5 equals 80, bring the 18 down. it will be -12+80 which equals 68..positive 68 as the remainder. hope i helped

Answer:

13) Rectangle

14) parallelogram

15) co ordinates areD (0,a) andE (c,b)

16) co ordinates are D(0,b) and E(a,0)

17)(-1,1) (4,1) (-1,4)

18)(0,0) (a,0) (a,a) (0,a)

Step-by-step explanation:

<h3>13)</h3><h3>Rectangle</h3>

The opposite sides of a rectangle are parallel and equal

left height = right height

(by using distance formula)

(0,3),(2,-2) = (5,5),(7,0)

√(2-0)²+(-2-3)² = √(7-5)²+(0-5)²

√(2)²+(-5)² = √(2)²+(-5)²

√4+25 = √(2)²+(-5)²

√29 = √29 hence equal

<h3>14)</h3><h3>parallelogram</h3>

The opposite sides of a rectangle are not equal

left height = right height

(by using distance formula)

(0,0),(3,-4) = (3,4),(7,0)

√(3-0)²+(-4-0)² = √(7-3)²+(0-4)²

√(3)²+(-4)² = √(5)²+(-4)²

√9+16 = √(25)+(16)

√(25) ≠√41

5 ≠ √41

<h3>15)</h3><h3>co ordinates are D(0,a) and E(c,b)</h3><h3>16)</h3><h3>co ordinates are D(0,b) and E(a,0) </h3>

since rhombus have equal opposite sides

<h3>17)</h3><h3>(-1,1) (4,1) (-1,4)</h3><h3>18)</h3><h3>(0,0) (a,0) (a,a) (0,a)</h3><h3 />

The function f(x) = 2x2 + 6x - 12 has a domain consisting of the integers from -2 to 1, inclusive. Which set represents the corr
Dimas [21]

Answer:

[-16,-4]

Step-by-step explanation:

We are given that

f(x)=2x^2+6x-12

Domain=[-2,1]

We have to find the set of range values of f(x).

Substitute x=-2

f(-2)=2(-2)^2+6(-2)-12

f(-2)=-16

Substitute x=1

f(1)=2(1)+6(1)-12=-4

Range of f(x)=[-16,-4]

Hence, the set of range values of f(x)

[-16,-4]
