Answer:

D

Step-by-step explanation:

Given

P = 2(l + b) ← distribute parenthesis

P = 2l + 2b ( subtract 2b from both sides )

P - 2b = 2l ( divide both sides by 2 )

\frac{P-2b}{2} = l → D

Answer:

D

Step-by-step explanation:

You have P=2(l+b)

First, you expand the right side of the equation and get P=2l+2b

Next, you subtract 2b from each side to get P-2b = 2l

Then divide by 2 to get l = (P-2b)/2

Does this graph represent a function? Why or why not?
malfutka [58]

Answer:

Yes.

Step-by-step explanation:

It is a function because it passes the vertical line test. Each x-value has just one y-value. If the relation had any x-values that had several y-values, it would just be a relation. But this one is a function.

Hope this helps!

mart [117]

Answer:

4^n-1

Step-by-step explanation:

So given sequence is a geometric sequence where terms increase or decrease by a constant common ratio(r)

Formula to find terms in Geometric sequence is " ar^n-1 where a is first term , r is common ratio and n is number of items

In this case , first term (a) is 1 , common ratio(r) is succeeding term/preceding term = 4/1 = 4 and number of items be (n).

Applying "ar^n-1 " we get,

1*4^n-1 which is , 4^n-1

Thats the formula which represents the situation....

netineya [11]

Answer:

80.7 inches

Step-by-step explanation:

circumference = 2 * pi * r

2 * pi * r = 507 inches

r = (507 inches)/(2 * pi)

r = (507 inches)/(2 * 3.14159)

r = (507 inches)/(6.2832)

r = 80.7 inches
