$x^2+2x=35$
$x^2+2x+1=35+1$
$(x+1)^2=36$
$(x+1)^2=6^2$
$x+1=6\lor x+1=-6$
$x=6-1\lor x=-6-1$
$\boxed{x=5\lor x=-7}$

The width-to-height ratio of a certain computer monitor

Mnenie [13.5K]

<h2>24 inches</h2>

Step-by-step explanation:

It is given that $\frac{\textbf{width of computer monitor}}{\textbf{height of computer monitor}}=\frac{16}{9}$

It is given that $\text{height of computer monitor}=13.5$

$\text{width of computer monitor} =\text{height of computer monitor}\times \frac{16}{9}$

$\text{width of computer monitor}=13.5\times \frac{16}{9} =\frac{216}{9} =24$

Hence the required width in inches is 24.

Triangle ABC has the following coordinates: A(4 , 5), B(5 , 3), and C(2 , 3). Part A: If triangle ABC is dilated by a scale fact

Kobotan [32]

The new coordinates of A'B'C' creates a triangle that is larger than ABC.

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>translation, reflection, rotation and dilation.</em>

If a point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky).

Given that:

Triangle ABC has the following coordinates: A(4 , 5), B(5 , 3), and C(2 , 3)

If it is dilated by a scale factor of 3, the new point is at:

A'(12, 15), B'(15, 9) and C'(6, 9)

Therefore the new coordinates of A'B'C' creates a triangle that is larger than ABC.

I'm really confused, can you please help me

Anika [276]

Answer: y=8

Step-by-step explanation:

Since DF is bisected, it means but in half. This means DU and UF are equal in length. We can set them equal to each other to find y.

2y=16 [divide both sides by 2]

y=8

Suppose you are doing a puzzle. After 10 minutes, you have 275 pieces placed, and after 22 minutes, you have 395 pieces placed.

LenKa [72]

Answer:

600 pieces

Step-by-step explanation:

pieces/ time(min) = (395-275) / (22-10) = 120/ 12 = 10

10= x (pieces) / 60(min) => x = 60×10 => x = 600 pieces
