Put x on one side of the equation
6x=(76+22)
6x=98
x=98/6
Simplify
x=49/3
X² = 16
x = ±√16
x = <span>±4
</span>The roots of this equation are -4 and 4
<span>Сorrect answer is third from above</span>

Queremos resolver un problema sobre porcentajes, donde conociendo el porcentaje que un dado número representa, queremos encontrar el número equivalente al 100%.
Veremos que el número total de arboles es 250.
------------------------------------
Sabemos que el 18% de los arboles son almendros y el resto son naranjos, es decir, el porcentaje de naranjos es 100% - 18% = 82%
Y sabemos que hay 45 almendros.
Entonces el <u>18% del número total de arboles es 45.</u>
Es decir, si hay N arboles en total, el 18% de N es igual a 45, esto se puede escribir como:
(18%/100%)*N = 45
0.18*N = 45
N = 45/0.18 = 250
Así podemos concluir que hay un total de 250 arboles en la plaza.

Answer:
Part a) By alternate interior angles
Part b) By vertical angles
Part c) By AAA (Angle-Angle-Angle) Similarity Theorem
Part d) Triangles ABC and CDE are similar
Part e)
or 
Step-by-step explanation:
Part a)
we know that
If AB is parallel to DE
then
m<1=m<4 ------> by alternate interior angles
Part b)
we know that
m<5=m<6 -------> by vertical angles
Part c) we know that
The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal
so
m<1=m<4
m<5=m<6
m<3=m<2
Part d) we know that
If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
therefore
Triangles ABC and CDE are similar
Part e) Find the length side of b
Remember that
If two figures are similar, then the ratio of its corresponding sides is equal
so

substitute the values
