An alternating series is an infinite series that takes the form:
∑(-1)ⁿa_n
a_n>0 for every value of n. The signs of the general terms alternate between positive and negative.
Thus from the above definition, the series given by <span>2, 3, 6, 8, . . . does not fit the definition of alternating series.</span>

The side lengths of a rectangle are all multiplied by 5. What happens to its perimeter?

stiv31 [10]

Answer:

The perimeter is multiplied by 5.

Step-by-step explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with sides l and w is given by:

$P = 2(l + w)$

The side lengths of a rectangle are all multiplied by 5.

This means that $l = 5l, w = 5w$ . So

$P_M = 2(5l + 5w) = 2*5(l+w) = 10(l + w)$

What happens to its perimeter?

The rate is:

$\frac{P_M}{P} = \frac{10(l+w)}{2(l+w)} = 5$

The perimeter is multiplied by 5.

Red and grey bricks were used to build a decorative wall. The number of red bricks and grey bricks was 5/2. There were 140 brick

ozzi

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.
