What is [tex]-9.2(8x - 4) + 0.7(2 + 6.3x)[/tex] simplified?

A. [tex]-69.19x - 32.39[/tex]
B. [tex]-69.19x + 38.2[/tex]
C. [tex]-72.2x + 41.21[/tex]
D. [tex]75x - 338.2[/tex]

Answer :

Sure! Let's simplify the expression step-by-step:

The expression we need to simplify is:

[tex]\[ -9.2(8x - 4) + 0.7(2 + 6.3x) \][/tex]

1. Distribute -9.2 through the first parenthesis:

[tex]\[-9.2 \times 8x = -73.6x\][/tex]

[tex]\[-9.2 \times (-4) = 36.8\][/tex]

So, the first part becomes [tex]\(-73.6x + 36.8\)[/tex].

2. Distribute 0.7 through the second parenthesis:

[tex]\[0.7 \times 2 = 1.4\][/tex]

[tex]\[0.7 \times 6.3x = 4.41x\][/tex]

So, the second part becomes [tex]\(1.4 + 4.41x\)[/tex].

3. Combine like terms:

First, let's combine the terms involving [tex]\(x\)[/tex]: [tex]\(-73.6x + 4.41x\)[/tex].

[tex]\[-73.6x + 4.41x = -69.19x\][/tex]

Next, combine the constant terms: [tex]\(36.8 + 1.4\)[/tex].

[tex]\[36.8 + 1.4 = 38.2\][/tex]

So, the simplified form of the expression is:

[tex]\[ -69.19x + 38.2 \][/tex]

Therefore, the correct option is [tex]\(-69.19x + 38.2\)[/tex].
