Answer:
length is 8
width is 12
Step-by-step explanation:
the equation to solve this would be
x*(x+4)=96
you isolate the variable by dividing each side by factors that doesn't contain the variable
X would then equal 8
length is 8
width is 8+4= 12
The square root of 144x^2 = 12 x
and square root of + 81 = 9 or -9
if this polynomial were a perfect square then its factors would be
(12x - 9)(12x - 9)
but its not a perfect squre because (12x - 9)(12x - 9) = 144x^2 - 216x + 81.
$20,000 is between $15,000 and $49,999, so we'll use the interest rate of 6.5% (see row 3)
r = 6.5% = 6.5/100 = 0.065
We'll use the decimal form of the interest rate as it is most common for financial math problems.
P = 20,000 is the amount deposited
t = 1 year is the amount of time
We will plug those values into the formula
i = P*r*t
to get the following:
i = P*r*t
i = 20000*0.065*1
i = 1300
So Mark earns $1,300 in simple interest each year.
Answer:
7m = 50.75
Step-by-step explanation:
5m=36.25
We can solve this for m by dividing each side by 5
5/5m=36.25/5
m = 7.25
We want to find 7m
7(7.25) = 50.75
