#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
Answer:
The difference between a median and altitude of a triangle is given below :
Altitude is the perpendicular line drawn from a vertex of a triangle to its opposite side
.But a median of a triangle is a segment connecting a vertex to the midpoint of its opposite side.
Step-by-step explanation:
The difference between a median and altitude of a triangle is given below :
Altitude is the perpendicular line drawn from a vertex of a triangle to its opposite side
.But a median of a triangle is a segment connecting a vertex to the midpoint of its opposite side.
-3(2r+7)=3
distribute -3
-6r-21=3
add 21 to both sides, this causes the 21 on the left to cancel itself out.
-6r=24
divide each side by -6, this causes the -6 on the left side to cancel itself out.
r=-4
