Answer:
Answer B and C
Step-by-step explanation:
Z is the center of the circle passing through H,G,J:
HZ=85=ZG=ZJ ==> ZJ=85 : B is true
HK=KG=136/2=68: C is true.
(3x+12)-5x=22
-15x^2-60x=22
-15x^2-60x-22=0
x=-b/2a
x=60/-30
x=-2
Answer:
Step-by-step explanation:
p^8 q^6 / p ^4 q^3
In this expression the base of numerator and denominator is same:
We will change the division into multiplication and the denominator will become numerator will negative exponents:
p^8 q^6 * p ^-4 q^-3
Now simplify the terms with same base
The exponents of the same base will be added
=p^8+(-4) q^6+(-3)
=p^8-4 q^6-3
=p^4 q^3
The answer is p^4 q^3....

Step-by-step explanation:
Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.
You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3
10√6 / 2 * √
3 = 15
