X² + x - 20 = 0
x² = x * x
x = the sum of the factors of -20
-20 ⇒ 1 x 20
2 x 10
- 4 x 5 ⇒ only these factors can arrive to a sum of 1
(x - 4)(x + 5) = x(x+5) - 4(x+5) = x² + 5x - 4x - 20 = x² + x - 20
x - 4 = 0
x = 4
x + 5 = 0
x = -5
B would be the answer because if you were to search up a picture of alternate interior angles, it would be the same as <CAD and <ACB
Answer:
V=28.203 yd.
Step-by-step explanation:
V= 1/3 Bh. B= 1/2(l×w) h= 7.9
V= 1/3( 10.71×7.9) B= 1/2(3.4×6.3) l=3.4
V=1/3(84.609) B= 1/2(21.42) w=6.3
V=28.203 B= 10.71

Change your fractions into decimals.
1/2 = 0.5
1/3 = 0.33 (rounded)
5.5 x 2.33 = 12.815
12.815 is your answer
hope this helps
