<h2>Answer:</h2>

\boxed{15.4z-12}

<h2>Explanation:</h2>

Here we have the following expression:

7.4z-5(-1.6z+2.4)

We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

7.4z-5(-1.6z)-5(2.4) \\ \\ Remember \ these \ rules: \\ \\ (+)(+)=+ \\ \\ (-)(-)=+ \\ \\ (-)(+)=+ \\ \\ (+)(-)=- \\ \\ \\ So: \\ \\ 7.4z+8z-12 \\ \\ \\ Combining \ like \ terms \ 7.4z \ and \ 8z: \\ \\ \boxed{15.4z-12}

For the data in the table, write an equation for the direct variation.
melisa1 [442]

The equation of direct variation is,

\begin{gathered} y=kx \\ k=\frac{y}{x} \end{gathered}

Substitute the values of <em>y</em> and <em>x</em>.

\begin{gathered} k=\frac{5.4}{4} \\ k=1.35 \end{gathered}

So, the obtained equation will be <em>y</em>=1.35(x).

Let's check with the values of <em>x</em>.

1) If <em>x</em>=4

\begin{gathered} y=1.35x \\ y=1.35(4) \\ y=5.4 \end{gathered}

2) If <em>x</em>=2

\begin{gathered} y=1.35x \\ y=1.35(2) \\ y=2.7 \end{gathered}

3) If <em>x</em>=-2

Answer:

Length of rectangle = 16 cm

Width of rectangle = 4 cm

Step-by-step explanation:

Given:

Area of rectangle = 64 cm²

Find:

Length and width

Computation:

Assume;

Length of rectangle = a

So,

Width of rectangle = a -12

Area of rectangle = l x b

So,

a(a-12) = 64

a² - 12a - 64 = 0

a² - (16-4)a - 64 = 0

a² - 16a+ 4a - 64 = 0

a (a-16) + 4(a-16)= 0

(a-16)(a+4) = 0

a= 16 , a = -4

So,

Length of rectangle = 16 cm

Width of rectangle = a -12

Width of rectangle = 16 -12

Width of rectangle = 4 cm
