If f(a)=(a•a•a)-(a•a) + a-1 what is the value of f(-3)?

Elena L [17]

Answer:

-40

Step-by-step explanation:

f(a) = a³ - a² + a - 1

f(-3) = (-3)³ - (-3)² + (-3) - 1

f(-3) = (-27) - (9) + (-3) -1

f(-3) = -27 - 9 -3 - 1

f(-3) = -40

Like terms have the same variable. For example, 3x and 2x are like terms, so

3x+2x = 5x

What is the simplified form of the following expression? 7(3sqrt2x)-3(3sqrt16x)-3(3sqrt8x)

coldgirl [10]

Assignment: $\bold{Simplify \ Equation: \ 7\left(3\sqrt{2}x\right)-3\left(3\sqrt{16}x\right)-3\left(3\sqrt{8}x\right)}$

<><><><><><><>

Answer: $\boxed{\bold{3\sqrt{2}x-36x}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Remove Parenthesis (a) = a

$\bold{7\cdot \:3\sqrt{2}x-3\cdot \:3\sqrt{16}x-3\cdot \:3\sqrt{8}x}$

[ Step Two ] Simplify Equations

$\bold{7\cdot \:3\sqrt{2}x: \ 21\sqrt{2}x}$

$\bold{3\cdot \:3\sqrt{16}x: \ 36x}$

$\bold{3\cdot \:3\sqrt{8}x: \ 18\sqrt{2}x}$

[ Step Three ] Rewrite Equation

$\bold{21\sqrt{2}x-36x-18\sqrt{2}x}$

[ Step Four ] Add Similar Elements

$\bold{21\sqrt{2}x-18\sqrt{2}x=3\sqrt{2}x}$

[ Step Five ] Rewrite Equation

$\bold{3\sqrt{2}x-36x}$
