There are several ways to solve this problem. The easiest one is by trigonometry. I am going to apply this method. If you didn't see trigo yet, I will use the triangles semi equilateral.
Let BD, be the wall on the left and CE on the right (B and D = base of the wall)
1) In Δ BAD, angle BAD = 60°→→ tan (60) =(opposite side)'(adjacent) =BD/DA
tan (60) = 60/DA , but tan (60) = √3 →→√3 = 60/DA or DA = 60/√3
And DA = 34.64
2) In Δ ACE, angle CAE = 30°→→ tan (30) =(opposite side)'(adjacent) =EC/AE
tan (30) = 40/AE , but tan (30) = √3/3 →→√3/3 = 40/AE or AE = (40)/(√3/3)
And AE = 68.28
3) Distance between walls = DA + AE = 34.64 + 68.28 = 103.92
(If you didn't study trigo yet, do let me know then we will solve it with the semi equilateral triangles
B is the answer , because in functions, we can’t have two X for one Y
Answer:
petunias, snapdragons, then pansy
Step-by-step explanation:
Ok first, lets find the percentage of 18 out of 40: 18/40= 0.45
The 21 out of 50= 21/50= 0.42
Lastly, 12/30= 0.40
And its very simple to put from least to greatest:
0.40, 0.42, 0.45
Hope this helped ;)
Answer:
esto literalmente no significa nada jajaja
y un poco sé la respuesta, pero no quiero decírtelo y jeje

Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
