Answer:

Step-by-step explanation:

They give you the equation, you must substitute the x values into the equation to find the y values.

Example on top equation:

y=-5x so the y values would be

y=-5(-1)=5

y=-5(0)=0

y=-5(1)=-5

y=-5(2)=-10

What are the zeros of g(x)=x(x^2-25)(x^2-3x-4)

denis-greek [22]

Answer:

$\large\boxed{x\in\{-5,\ -1,\ 0,\ 4,\ 5\}}$

Step-by-step explanation:

The zeros of g(x):

$g(x)=x(x^2-25)(x^2-3x-4)\to g(x)=0\\\\x(x^2-25)(x^2-3x-4)=0\iff x=0\ \vee\ x^2-25=0\ \vee\ x^2-3x-4\\\\x^2-25=0\qquad\text{add 25 to both sides}\\x^2=25\to x=\pm\sqrt{25}\\x=-5\ \vee\ x=5\\\\x^2-3x-4=0\\x^2+x-4x-4=0\\x(x+1)-4(x+1)=0\\(x+1)(x-4)=0\iff x+1=0\ \vee\ x-4=0\\x=-1\ \vee\ x=4$

ILL MARK YOU AS BRAINLIEST, RATE YOU A 5, AND THANK YOU! 70 POINTS!

nadya68 [22]

Answer:

Step-by-step explanation:

From the net:

S.A. = 2(25 in²) + 4(60 in²) = 50 in² + 240 in² = 290 in²

From the model:

The formula of a Surface Area of a rectangular prism:

S.A. = 2(lw + lh + wh)

l - length

w - width

h - height

We have l = 5 in, w = 5 in, and h = 12 in. Substitute:

S.A. = 2(5 · 5 + 5 · 12 + 5 · 12) = 2(25 + 60 + 60) = 2(145) = 290 in²
