Step-by-step explanation:
we see the common difference is
a2-a1 = 11x + 9 - 4x - 5 = 7x + 4
an = an-1 + (7x+4) = a1 + (n-1)×(7x+4)
for a7 we have then
a7 = 4x + 5 + 6×(7x +4) = 4x + 5 + 42x + 24 = 46x + 29
Area = length x width
with a little algebra we can reorganize the equation and solve for length...
A = L x W
A/W = L
So the statement divide the area by the width is TRUE.
Answer:
2 and 2 1/2
Step-by-step explanation:
3*3/4 = 9/4 This is slightly greater than 2
It lies between 2 and 2 1/2
Answer:
the answer is 25
Step-by-step explanation:
45+30=100-w
then your going to subtract 45 on both sides. So 100-45 is 55.
so now your equation looks like this
30 = 55 - w
subtract 55 on both sides so you will have -25 = -w. Then your going to divide -w on both sides and you will have positive 25
