krek1111 [17]

Answer:

$\large\boxed{A.\ -10x^2-33x+1}$

Step-by-step explanation:

$6x(x-4)-16x^2-(9x-1)\qquad\text{use the distributive property}\\\\=(6x)(x)+(6x)(-4)-16x^2-9x-(-1)\\\\=6x^2-24x-16x^2-9x+1\qquad\text{combine like terms}\\\\=(6x^2-16x^2)+(-24x-9x)+1\\\\=-10x^2-33x+1$

It takes Harrison 1 1/2 hours to finish his history project it takes Miles 3 2/3 hours to finish his science project. How many t

solniwko [45]

Answer: The answer is $2\dfrac{4}{9}~\textup{times}.$

Step-by-step explanation: Given in the question that

Time taken by Harrison to finish his history project is given by

$t_1=1\dfrac{1}{2}=\dfrac{3}{2}~\textup{hours}.$

and the time taken by Kiles to finish his science project is

$t_2=3\dfrac{2}{3}=\dfrac{11}{3}~\textup{miles}.$

Let the time taken by Miles to finish his science project be 'p' times that of the time taken by Harrison to finish his history project.

Therefore,

$t_2=p\times t_1\\\\\Rightarrow p=\dfrac{t_2}{t_1}=\dfrac{\frac{11}{3}}{\frac{3}{2}}=\dfrac{11}{3}\times \dfrac{2}{3}=\dfrac{22}{9}=2\dfrac{4}{9}.$

Thus, Miles take $2\dfrac{4}{9}$ times more time than Harrison.
