marshall27 [118]4 years ago
7 0

Answer:

Step-by-step explanation:

put x=1

1 )  1  7  7  -15

 |      1  8   15

  ----------------

    1  8  15 | 0

so x-1 is a factor.

x²+8x+15=0

x²+3x+5x+15=0

x(x+3)+5(x+3)=0

(x+3)(x+5)=0

so x-1,x+3,x+5 are factors.

Give the Factors (x- 8)(x + 3), what are the Roots?​
masya89 [10]

Answer:

\large\boxed{x=-3\ \vee\ x=8}

Step-by-step explanation:

(x-8)(x+3)=0\iff x-8=0\ \vee\ x+3=0\\\\x-8=0\qquad\text{add 8 to both sides}\\\\x-8+8=0+8\\\\\boxed{x=8}\\\\x+3=0\qquad\text{subtract 3 from both sides}\\\\x+3-3=0-3\\\\\boxed{x=-3}

Three brothers Adam, Paul, and Jake are standing on a large carnival scale. The total weight for all three boys reads 180 pounds
tatyana61 [14]

Answer:

Paul = 30 pounds

Step-by-step explanation:

If Adam (A), Paul(P) and Jake(J) together they weigh 180 pounds (A+P+J=180); and Adam and Jake is 2:3 (2A=3J) then how much does paul weigh?

A+P+J=180, 2A=3J, J=60 we have; A=(3/2)J=(3/2)*60 → A=90, 90+P+60=180 →

P=180-90-60 → P=30

Using the equation 4x^3-6x^2-144x+8, find the function values f(-3) and f(-4) at the interval {-4,5}
Leto [7]

Answer: f(-3) = 278, f(-4) = 232

Step-by-step explanation:

f(x) = 4x³ - 6x² - 144x + 8

f(-3) = 4(-3)³ - 6(-3)² - 144(-3) + 8

f(-3) = 4(-27) - 6(9) - 144(-3) + 8

f(-3) = 278

f(-4) = 4(-4)³ - 6(-4)² - 144(-4) + 8

f(-4) = 4(-64) - 6(16) - 144(-4) + 8

f(-4) = 232
