Answer:
x=21
Step-by-step explanation:
x=9+12 x=21
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
Answer:
3,125 i think sorry if this is incorrect....
Step-by-step explanation:
Answer:
P = $ 3,125.00
Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
P = 500 / ( 0.08 × 2 ) = 3125
P = $ 3,125.00
The principal required to
accumulate interest of $ 500.00
on a rate of 8% per year for 2 years is $ 3,125.00.
X^4 y^2/3. Space 3^4=81 the fourth root of 81 is 3
