Area= Length × Width
Area=(2x-4)(x+5)
Area=2x(x+5)-4(x+5)
Area=2x^2+10x-4x-20
Area=2x^2+6x-20

The answer is C. 2x^2+6x-20

Area = Length * Width
A = (2x - 4) * (x + 5)
A = 2x² +10x-4x - 20
A = 2x² + 6x - 20

In short, Your Answer would be Option C

Hope this helps!

The Johnsons spent a total of ​$69.96 for dinner at their favorite restaurant last night. If this cost included a ​20%​ tip, how
enyata [817]
It would be 55.97

To find this you find what 20% of 69.96 is and subtract that number from 69.96 (in this case that number would be 13.99) So you would find your answer of 55.97

Answer:

The image below will explain the question

To figure out the length of portion BC, we will use the trigonometric ratio below

\begin{gathered} \sin\theta=\frac{opposite}{hypotenus} \\ oppsite=BC \\ hypotenus=8in \\ \theta=35 \end{gathered}

By substituting the values, we will have

\begin{gathered} \sin(\theta)=\frac{oppos\imaginaryI te}{hypotenus} \\ \sin35=\frac{BC}{8} \\ cross\text{ multiply, we will have} \\ BC=8\sin35 \end{gathered}

Hence,

The final answer is

\Rightarrow8\sin35^0

The FOURTH OPTION is the right answer
