Answer:
45 miles per hour.
Step-by-step explanation:
you have to times 15 by 3 to get 45
and 20 times three is 60
L=0×r
l=3π/5×7
l=22×3×7÷7÷5
l=66/5
l=13.2 units
A triangle is equal to 180. Using that, we can make a equation.
6x-3 + 3x+6 + 5x = 180
Combining the like terms, we get:
14x+3 = 180
Subtract 3 on both sides.
14x = 177
Finally, divide 177 by 14.
x = 177/14 or about 12.6
Answer(C)
√(9x^2)= 3x
√(18y^2)=3y/√2= 3y/√2 X √2/√2
=3√2y/2
