Answer: 4x^2 - 10x - 6

Step-by-step explanation:

You can use FOIL to do this. First terms, Outer terms, Inner terms, Last terms.

(x - 3)(4x + 2)

First terms: x * 4x = 4x^2

Outer terms: x * 2 = 2x

Inner terms: -3 * 4x = -12x

Last terms: -3 * 2 = -6

Now add these together:

4x^2 + 2x - 12x - 6 = 4x^2 - 10x - 6

Answer:

4x^2 - 10x - 6

Step-by-step explanation:

If you truly want to multiply these binomials, remove the " + " sign and replace it with " * " for multiplication:

(x - 3) (4x + 2) = 4x^2 + 2x - 6 - 12x

Combining like terms, we get 4x^2 - 10x - 6

Find the slope of the line through the points (7,4) and (-10,4).

algol [13]

Answer:

Step-by-step explanation:

We have 2 points on a line so we can use the slope formula

m = (y2-y1)/(x2-x1)

= (4-4)/(-10-7)

= 0/-17

= 0

Answer:

Answer is given below with explanations.

Step-by-step explanation:

Answer is option 1) 85 : 51

$given \: that \: \\ triangle \: SPT \: is \: similar \: to \: triangle \: QPR \\ corresponding \: sides \: of \: similar \: \\ triangles \: are \: in \: proportion \\ then \: \\ \frac{SP}{ QP} = \frac{PT }{ PR} \\ \frac{3x}{3x + 24} = \frac{51}{85} \\ taking \: reciprocal \: on \: both \: sides \\ \frac{3x + 24}{3x} = \frac{85}{51}$

Option 1 is correct.

Find the measure of arc DF in degrees, given that the shaded region has an area of 45.27 square centimeters. If necessary, round

marishachu [46]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\qquad 
\begin{cases}
r=radius\\
\theta =angle\ in\\
\qquad degrees\\
----------\\
r=6\\
A=45.27
\end{cases}\implies 45.27=\cfrac{\theta\pi \cdot 6^2}{360}
\\\\\\
45.27\cdot 360=\theta \pi 6^2\implies \cfrac{45.27\cdot 360}{36\pi }=\theta
\\\\\\
144.09888547540\approx\theta \implies 144.10^o\approx\theta =\widehat{DF}
\\\\\\
\textit{now, that gives you the central angle, however}\qquad \theta =\widehat{DF}$

bearing in mind that, arcs get their angle measurement from the central angle they're in. Thus, the measure of that central angle, is the same measure in degrees of that arcDF.
