24x-16 is 8*(3x-2). Therefore, there are 8 rows of trees.
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
Answer:
x=6
Step-by-step explanation:
-21+3x=-3
+21 +21
3x=18
/3 /3
x = 6
