A circular mirror is surrounded by a square metal frame. The radius of the mirror is 5x. The side length of the metal frame is 1

Aleks04 [339]

Answer:

$-25x^{2} (\pi -9)$

Step-by-step explanation:

The area of the metal frame is equal to the area of the square minus the area of the circle.

The area of the square is the side length squared:

$(15x)^{2}$

$=225x^{2}$

The area of the circle is $\pi r^{2}$ , with $r$ being the radius:

$\pi (5x)^{2}$

$=\pi *25x^{2}$

$=25\pi x^{2}$

Now find the area of the metal frame:

$225x^{2} -25\pi x^{2}$

$25x^{2} (9-\pi )$ Factor out the GCF, $25x^{2}$

$-25x^{2} (\pi -9)$ Factor out a $-1$

Answer:

25x ²−49y ²

Step-by-step explanation:

We need to find product of (5x+7)(5x−7y)

By using identity (a+b)(a−b)=a −b ²

We have a=5x,b=7y

Thus (5x+7y)(5x−7y)=(5x) ²−(7y)

4x+7y=-<br> 20<br> 2x-5 y=-10

Diano4ka-milaya [45]

Answer:

x = -5 , y = 0

Step-by-step explanation:

Solve the following system:

{4 x + 7 y = -20 | (equation 1)

2 x - 5 y = -10 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{4 x + 7 y = -20 | (equation 1)

0 x - (17 y)/2 = 0 | (equation 2)

Multiply equation 2 by 2/17:

{4 x + 7 y = -20 | (equation 1)

0 x - y = 0 | (equation 2)

Multiply equation 2 by -1:

{4 x + 7 y = -20 | (equation 1)

0 x+y = 0 | (equation 2)

Subtract 7 × (equation 2) from equation 1:

{4 x+0 y = -20 | (equation 1)

0 x+y = 0 | (equation 2)

Divide equation 1 by 4:

{x+0 y = -5 | (equation 1)

0 x+y = 0 | (equation 2)

Collect results:

Answer: {x = -5 , y = 0
