$(7x + 3)(4x -5)$

$7x*4x+7x(-5)+3*4x+3(-5)$

$7*4xx-7*5x+3*4x-3*5$

$=28x^2-23x-15$

Hope this helps!

Thanks!

What is f(3) for the quadratic function f(x)=2x2 + x – 12? F -3 G 3 H 6 I. 9

PolarNik [594]

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

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

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9

I’m sure this is easy but i'm gonna ask anyway

Arada [10]

No, it's always okay to ask if you don't understand a question. Anyway, for this problem, we just have to plug in the value for V to solve for P :

$P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}$

A number to the power of 1/3 is the same as taking a cube root.

$P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20$

The perimeter of one face of the cube is 20m.
