4. Find CD and X . (3 points) x ^ 3 + 20 30 D x ^ 8 + 22x - 120 will mark brainliest

CD = 15

x = 5

Step-by-step explanation:

Since BF ≅ FD and AE ≅ EC, then

So,

2(x - 5)(x + 16) = 0

x = 5  or x = -16

If x = 5, then CD =  

Ix x = -16, then CD = will be a negative number which it cannot be.

squares, rhombus, rectangles

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
