A picture inside a frame is 2 inches longer than it is wide. The picture is in a frame that has a width of 3 inches on each side

geniusboy [140]

Answer:

The dimensions of the frame are 15 in x 13 in

Step-by-step explanation:

Let

x ----> the length of the picture

y ----> the width of the picture

we know that

$x=2+y$ -----> equation A

The area of the picture, including the frame is

$A=(x+6)(y+6)$

$A=195\ in^2$

$195=(x+6)(y+6)$ ----> equation B

substitute equation A in equation B

$195=(2+y+6)(y+6)$

solve for y

$195=(y+8)(y+6)\\y^2+6y+8y+48=195\\\\y^2+14y-147=0$

solve the quadratic equation by graphing

The solution is y=7 in

see the attached figure

<em>Find the value of x</em>

$x=2+7=9\ in$

Find the dimensions of the frame

$x+6=9+6=15\ in$

$y+6=7+6=13\ in$

therefore

The dimensions of the frame are 15 in x 13 in

bezimeni [28]

Answer:

Step-by-step explanation:

<em>Midpoint Formula:</em>

$\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}$

$\frac{3+1}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$\frac{8+-4}{2}$ ⇒ $\frac{8-4}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$(2,2)$
