4th term / second term = a1r^3 / a1r = r^2
so r^2 = 45/4 / 20 = 45/80 = 9/16
so r = sqrt 9/16 = 3/4 answer
Answer:
x = -4/3
Step-by-step explanation:
to solve for the value of x in the expression 2/3 (3x+2)=1x
we have
2(3x +2) /3 = x
6x + 4 /3 = x
using cross multiply technique
6x + 4 = 3 × x
6x + 4 = 3x
collect the like terms
6x -3x = -4
3x = -4
divide both sides by the coefficient of x
3x/3 = -4/3
x = -4/3
Answer:
17.95
Step-by-step explanation:
You subtract 964.36 from 982.31
Perimeter is 2l+2w
100 =2(30) + 2w
100 =60 + 2w
-60 -60
40 = 2w
w=20 meters.
Answer: D (bottom option)
Not Congruent
Step-by-step explanation:
Assuming the trapezoids are to scale, they are not the same shape. This means that they could not be congruent even if they were centered on top of each other.
