What is the length of DE? I need to find X. A: 8 B: 7 C: 5 D:6

The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.

So therefore, we can say it's 9:6, so DE is 6.

Add those equations together
<span>1. 4x = 16, x = 4

2. Multiple the second one by 2
2x+4y=22
4x-4y=-16
6x = 6, x = 1

3. Add them together
8x = 24, x = 3

Help me out here guys

D.

f(x) can be written as (x+2)(x-2)(x-1)
by using difference of two squares to expand x^2 - 4 whch yields 3 x intercepts

similarly, k(x) can be written as
x(x+5)(x-5) which also yields 3
x intercepts (0,-5, and 5)
