Answer:
option A
Step-by-step explanation:
Notice that you need to emulate the series: 1 + 5 + 25 + 125 + 625 (a five total term series)
with the indicated sums.
The first term in the your series (addition) has to be "1". This fact already gets rid of two of the suggested sums (B, and D) because their first term is .
So, now analyzing the options A and C, we notice that A has a sum from i=0 to 4 (which gives a total of five terms ao, a1, a2, a3, and a4, while option C has a total of six terms (from i = 0 to 5): a0, a1, a2, a3, a4, a5.
S, the obvious candidate is option A. So now evaluate the five terms corroborating that:
Therefore, option A is the answer
Answer:
Width also known as (W) = 1.5 meters
Area also known as (A) = 6 square meters
Length also known as (L) = ?
the formula to find Length is:
Step-by-step explanation:
Choice 3 is the answer
1.5x = 6
x=4
substitute 4 for the x
1.5(4)=6
1.5×4 = 6
so
6=6
so the answer is
1.5x=6
x=4
First of all, you can simplify the 4 at the numerator and the 14 at the denominator (they're both multiple of 2):
Now, rationalize a denominator means that you have to get rid of the square root, in order to have an integer denominator.
To do so, remember that you can always multiply any number by 1 without changing its value, and you can always think of 1 as a fraction where numerator and denominator are equal:
