Answer:
x = 25
Step-by-step explanation:
the line QC is parallel to BR
Then
x/15 = 40/24
Then
24x = 40×15
Then
24x = 600
Then
x = 600/24
Then
x = 25
Here we go!
The quadratic formula: x = [-b ± √(b2<span> - 4ac)]/2a
a = 1 (understood coefficient)
b = 12
c = -13
</span>
Okay, so here, we split into 2 problems. If 14 were positive:
If 14 were negative:
So,
840 : 360
(÷120) : ( ÷120)
7 : 3
