Lets l to be lenght, w width, p perimeter and a area:
a=lw
6400 ft²=lw
2(l+w)=p
2(l+w)=400 ft
l+w= 200 ft
l=200ft-w
substitute it instead of l to lw=6400ft²
(200-w)w=6400
200w-w²=6400
w²-200w+6400=0
(w-160)(w-40)=0
w = 160ft
w = 40ft
l=200-w
l=200-160 = 40ft
l= 200-40 =160ft
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.
It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1
Then, the explicit formula will be;
an = 20 + 5(n-1).
The correct answer is D.
Step-by-step explanation:
A. 4 x 3/5 = 4/4 x 3/5 = 12/20
B. 4x4 x 1/5 = 12/5
C. 12 + 1/5 = 4 x 3 x 1/5 = 12/5
D. 4 x 5/3 = 4 x 5 x 1/3 = 20/3
Answer:
x + 5 = 5
Step-by-step explanation:
Solution doesn't change as the x in the equation is 0 and the answer totals as 5 due to 5 plus 0 being 5
