$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \tt \dashrightarrow \:10 {x}^{2} - 25x + 15 = 0$

$\qquad \tt \dashrightarrow \:5(2x {}^{2} - 5x + 3) = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 5x + 3 = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 3x - 2x + 3 = 0$

$\qquad \tt \dashrightarrow \:x(2x - 3) - 1(2x - 3) = 0$

$\qquad \tt \dashrightarrow \:(x - 1)(2x - 3) = 0$

Therefore, the required factors are ~ (x - 1) and (2x - 3)

So, correct choice is B

For a triangle, m<1 =75 and m<3 =40 what does m<2 =?

VladimirAG [237]

Answer:

m<2 = 65

Step-by-step explanation:

The measures of angles 1 and 3 should be added together resulting in 115 degrees, and all triangles equal 180 degrees. Therefore, to find m<2, you have to subtract 115 from 180 resulting in a measure of 65 degrees.

The area of the sector of a circle with a radius of 8 centimeters is 125.6 square centimeters. The estimated value of pi is 3.14

tangare [24]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
\theta=\textit{angle in degrees}\\
r=radius\\
----------\\
r=8\\
A=125.6
\end{cases}
\\\\\\
360A=\theta\pi r^2\implies \cfrac{360A}{\pi r^2}=\theta\implies \cfrac{360\cdot 125.6}{\pi 8^2}=\theta$
