She could have hiked one 2 mile trail and one 1 mile trail or she could’ve hiked one 2.5 mile trail and another 0.5 mile trail
The angles 1 and 2 are right angles.
As stated in the question line l is perpendicular to line m and perpendicular lines create right angles
Hope this helps :)
Answer:
3*(5*x-7)-(15*x-21)=0
Step-by-step explanation:
3 • (5x - 7) - (15x - 21) = 0
Step 2 :
Equation at the end of step 2 :
0 = 0
Step 3 :
Equations which are always true :
area = pi x r^2
circumference = 2x pi x r or pi x d
1st one diameter = 9.5 cm
so radius = 9.5/2 = 4.75
area = 3.14 x 4.75^2 = 70.85 square cm
circumference = 3.14 x 9.5 = 29.83 cm
2nd one radius = 4
area = 3.14 x 4^2 = 50.25 square cm
circumference = 2 x 3.14 x 4 = 25.12 cm
