Answer:

  • x² - 8x + 12
  • x³ + 2x² - 15x - 36
  • x³ -2x² - 15x

Step-by-step explanation:

#1) Find the polynomial with roots at 2 and 6

  • (x -2)(x - 6) = x² - 8x + 12

#2) Find the polynomial with a double root at -3 and another root at 4

  • (x+3)(x+3)(x-4) = (x²+6x+9)(x-4) = x³ + 2x² - 15x - 36

#3) Find the polynomial with roots 0, -3 and 5

  • (x -0)(x+3)(x-5) = x(x²-2x - 15) = x³ -2x² - 15x

A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72

b=4a+c
b=4(18)+36
b=72+36
b=108

<span>Ricardo ended up with 18 golf balls. If he lost 4 on the course today, he then had 22 to start with today. This 22 total includes a box of 12 balls he bought today. This means he had 22 - 12 yesterday, making 10. Yesterday he lost 6 while playing. Ricardo had 16 balls to start with.</span>

Apply the distributive property to factor out the greatest common factor. 18d+12 =18d+12=18, d, plus, 12, equals? (plz help quic
qaws [65]

Answer:

Answer is 6(3 d+2)

Step-by-step explanation:

It is given the expression as 18d+12

Let's find common factor by prime factoring the terms.

18 d =2*3*3*d

12= 2*2*3

Common factors for both terms are 2, 3.

So, G C F = 2*3=6

Take out 6 from both terms to factor further.

We do get 6(3 d+2)

Pls help I don’t get it
Setler [38]

Answer:

x=-5, y=-2

Step-by-step explanation:

10x-9y=-32

2x-10y=10

(2x-10y)*5=10*5

10x-50y=50

(10x-9y)-(10x-50y)=-32-50

41y=-82

y=-82/2

y=-2

10x-9(-2)=-32

10x+18=-32

10x=-50

x=-5
