Answer:

$\frac{9}{16} in^3$

Step-by-step explanation:

First we need to find the volume of the cube. To do so, we need to multiply length × width × height

$\frac{3}{4} * \frac{3}{4} * 1 = 0.5625$

Convert to a fraction

$9/16 = 0.5625 = \frac{9}{16}$

Since we can not simplify this fraction to $\frac{1}{4}$ that is our answer. Since these cubes are in inches we need to add inch/in to the end. Also since this is the 3D cube we need to add ^3

$\frac{9}{16} in^3$

3) g(x)= x3 + x<br> h(x) = x + 4<br> Find g(0)h(0)

Arte-miy333 [17]

Answer:

$goh(x)=x^3+12x^2+49x+68$

Step-by-step explanation:

$g(x) = x^3+x$

$h(x)=x+4$

We have to find

$goh(x)$

$goh(x) = g(h(x))=g(x+4)$

If $g(x) = x^3+x$

$g(x+4) = (x+4)^3+(x+4)$

= $x^3+12x^2+49x+68$

Hence our answer is

$goh(x)=x^3+12x^2+49x+68$

How do I solve part A

seraphim [82]

Answer:

The solution of this expression is $x_{1} = -1$ and $x_{2} = -\frac{1}{2}$ .

Step-by-step explanation:

The procedure for solution of exercise A is described below:

1) We expand the expression.

2) The resulting expression is rearranged into the form of a second order polynomial.

3) Roots are found by Quadratic Formula.

Step 1:

$2\cdot x \cdot (x+1.5) = -1$

$2\cdot (x^{2}+1.5\cdot x) = -1$

$2\cdot x^{2} + 3\cdot x = -1$

Step 2:

$2\cdot x^{2}+3\cdot x +1 = 0$

Step 3:

$x_{1, 2} = \frac{-3\pm \sqrt{3^{2}-4\cdot (2)\cdot (1)}}{2\cdot (2)}$

$x_{1,2} = -\frac{3}{4}\pm \frac{1}{4}$

$x_{1,2} = \frac{-3\pm 1}{4}$

The solution of this expression is $x_{1} = -1$ and $x_{2} = -\frac{1}{2}$ .
