Answer:

DE=15 and AB=6

Step-by-step explanation:

Both Triangles are Similar. When looking at the length of AC, it is 3x smaller than CE. So we know that the triangle ABC is 3x smaller than CDE. Since we know that we can see that DE is 15 since it is 3x Larger than 5. We also know that AB is 6 since it is 3x smaller than 18

Solve Quadratic Equations by Factoring:
mr_godi [17]

Answer:

  1. x = 0 or 1
  2. x = ±i/4
  3. x = -5 (twice)

Step-by-step explanation:

Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.

1. x^2 -x = 0

  x(x -1) = 0 . . . . . x = 0 or 1

__

2. 16x^2 +1 = 0

This is the "difference of squares" ...

  (4x)^2 - (i)^2 = 0

  (4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)

__

3. x^2 +10x +25 = 0

  (x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2

I'll mark as brainliest if you get the answer correct with Explanation.
mrs_skeptik [129]

Answer:

25, 90, and 65

Step-by-step explanation:

so the measures have to add up to 180, because it's a triangle, and we know 25 and 90 ( the box corner thing means that angle is 90) so we add 25 and 90 to get 115, and then we subtract 115 from 180, which gets us 65.
