REY [17]4 years ago

Answer:

Below.

Step-by-step explanation:

( x + 2/5)(x + 3/7) = 0  will give x = -2/5, -3/7.

= x^2 + 2/5x + 3/7 x + ( 2^5 * 3/7) = 0

x^2 + (29/35)x + 6/35 = 0

Multiply through by 35:

35x^2 + 29x + 6 = 0 is the required equation.

To solve we factor it:

(7x + 3)(5x + 2) = 0

7x + 3 = 0 or 5x = 2 = 0

x = -3/7 , -2/5.

The polygons in each pair are similar. Find the missing side length.
Taya2010 [7]

Answer:

12

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

Is the red line a radius or diameter of the circle
insens350 [35]

The diameter of the circle would be a line going through the center of the circle connecting to both sides.

The radius of a circle would be a line only going to the the center, or in other words, half the circle.

I hope this makes sense!
