4 The perimeter of a regular pentagon is represented by the expression 35d - 25.
Komok [63]

The equivalent expression to Daryl's expression is -5 + 7d ⇒ d

Step-by-step explanation:

In a regular polygon of n-side

  • All sides are equal in lengths
  • All angles are equal in measures
  • Its perimeter is n × the length of one side

∵ The polygon is a pentagon

∴ n = 5

∵ The pentagon is regular

∴ The lengths of its 5 sides are equal

∵ Its perimeter = 5 × length of one side

∵ Its perimeter = 35d - 25

- Equate the two sides of the perimeter

∴ 5 × length of one side = 35d - 25

- Divide both sides by 5

∵ 35d ÷ 5 = 7d and 25 ÷ 5 = 5

∴ The length of one side = 7d - 5

Daryl's expression is 7d - 5

Now lets check the answers

a. 35d - 25 ⇒ No

b. 7d - 15 ⇒ No

c. 5(35 - 25) ⇒ No

d. -5 + 7d ⇒ Yes

e. (35d - 25) ⇒ No

The equivalent expression to Daryl's expression is -5 + 7d

Find the minimum and maximum possible areas for a rectangle measuring 4.15 cm by 7.34 cm. Round to the nearest hundredth. A. min
Shalnov [3]

This is probably in the context of a discussion of significant figures and accuracy.

When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to  41.155 cm

Similarly 7.34 really means between 7.335 and 7.345 cm.

The minimum area rectangle is 

4.145 \times 7.335 = 30.403575 \approx 30.40

The maximum area rectangle is

4.155 \times 7.345 =30.518475 \approx 30.52

Choice A
