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

1. Trevor saves 2/3 of the money he earns at his
AveGali [126]

Trevor will be saving less amount

<u>Step-by-step explanation:</u>

To know whether he will save less, more or the same amount, we need to find \frac{1}{4} \times \frac{2}{3} and then compare with \frac{2}{3}

Now, combine the fractions using the rule:

              \frac{a}{b} \times \frac{c}{d}=\frac{a \times c}{b \times d}

              \frac{1}{4} \times \frac{2}{3}=\frac{1 \times 2}{4 \times 3}=\frac{2}{12}=\frac{1}{6}

\frac{1}{4} \times \frac{2}{3} is less than the fraction \frac{1}{4}. Hence, concluding that Trevor will be saving less than \frac{2}{3} amount.

Classify each sequence as arithmetic, geometric, or neither by dragging it into the correct box.
garik1379 [7]

The sequences are classified, respectively, as:

Geometric, Arithmetic, Neither.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

In the first sequence, we have that:

q = \frac{45}{15} = \frac{15}{5} = \frac{5}{\frac{5}{3}} = \frac{\frac{5}{3}}{\frac{5}{9}} = 3

Hence it is a geometric sequence.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

In the second sequence, we have that:

d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5

Hence it is an arithmetic sequence.

<h3>What about the third sequence?</h3>

\frac{4}{3} \neq \frac{3}{2}, 1 - \frac{1}{2} \neq 2 - 1

Hence it is neither arithmetic nor geometric.
