Area=1/2bh
h=altitude
b=legnth of base
b is 3 times h
b=3h
divide by 3
b/3=h
area=1/2bh
subsitute b/3 for h
54=1/2(b)(b/3)
multiply bothsides by 2/1
108=b(b/3)
108=(b^2)/3
multipy both sides by 3
324=b^2
square root boh sides
18=b
legnth of base=18
Answer:
2 * 10 ^-4
Step-by-step explanation:
We need the first number to be between 1 and less than 10
.0002
2 * 10 ^ exponent
We move the decimal 4 places to the right. Since we move it to the right the exponent is negative and is the number of places we moved the decimal
2 * 10 ^-4
X=1 is the answer to your question
Answer:

Step-by-step explanation:
Solve for the value of
:

-The variable
cannot equal to
since division by zero is undefined. SO, you multiply both sides by
, which is the least common multiple of
,
, and
:


-Take
and subtract it from
:


-Divide both sides by
:


So, the value of
of
.
