It’s non-linear and it’s increasing.

It’s non-linear because it isn’t going in a straight line and you can tell it’s increasing by the way the line is going towards the right.

Factor 2x2 + 7x + 3. <br> (2x + 2)(x + 1) <br> (2x + 3)(x + 1) (2x + 1)(x + 3)
maks197457 [2]
<h3>Answer:</h3>

(2x + 1)(x + 3)

<h3>Step-by-step explanation:</h3>

It is probably easier to try the answer choices than to try to factor the expression yourself.

(2x + 2)(x + 1) = 2x² +4x +2

(2x + 3)(x + 1) = 2x² +5x +3

(2x + 1)(x + 3) = 2x² +7x +3 . . . . . correct choice

_____

<em>Constructed solution</em>

If you want to factor this yourself, you can look for factors of "ac" that add to give "b". That is, you want factors of 2·3 = 6 that add up to give 7. You don't have to look very far.

... 6 = 1·6 = 2·3 . . . . . . the first factor pair adds to give 7

Now, rewrite the x term using the sum of these numbers.

... 2x² +(1 +6)x +3

... 2x +x +6x +3 . . . . eliminate parentheses

... (2x +x) +(6x +3) . . . . group pairs of terms

... x(2x +1) +3(2x +1) . . . . factor each pair

... (x +3)(2x +1) . . . . . . matches the last selection

Is my solution correct?​
poizon [28]

Answer:

The area of the shaded sector is 51.2\pi \ units^{2}

Step-by-step explanation:

I assume that the problem is

Find the area of the shaded sector of the circle with radius equal to 16 units

step 1

Find the value of x

we know that

8x+2x=360\°-----> by complete circle

10x=360\°

x=36\°

The central angle of the shaded sector is 2x

2(36\°)=72\°

step 2

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

we have

r=16\ units

substitute

A=\pi (16)^{2}

A=256\pi\ units^{2}

step 3

Find the area of the shaded sector

we know that

A central angle of 360 degrees subtends an area of circle equal to 256\pi\ units^{2}

so

by proportion

Find the area of the shaded sector by a central angle of 72 degrees

\frac{256\pi}{360}=\frac{x}{72} \\ \\ x=256\pi *(72)/360\\ \\x=51.2\pi \ units^{2}
