Step-by-step explanation:

Since it is a regular pentagon, all five sides are equal and you know one side is x-3. Thus the equation would be: x-3 = 18.8/5

x - 3 = 18.8/5

= 3.76

x = 3.76 + 3

x = 6.76

Answer:

$18b - 15$

Step-by-step explanation:

<u>Step 1: Distribute </u>

$-3(-6b + 5)$

$(-3 * -6b) + (-3 * 5)$

$18b - 15$

Answer: $18b - 15$

<u>If needed solve for b </u>

$18b - 15 + 15 = 0 + 15$

$18b / 18 = 15 / 18$

VladimirAG [237]

Equating the formula (d is the diameter)

$\pi$ d^2/4 = 132.7
d^2 = 132.7*4/ $\pi$

Explain how you could use a number line to show that -4+3 and 3+(-4) have the same value.which property of addition states that

Anna007 [38]

For -4+3,
1. start with zero
2. move to left (-x axis) for 4 units (-4)
3. then move to right (+x axis) for 3 units (+3)

For 3+(-4)
1. Start with zero
2. Move the point to right side by 3 units (+3)
3. then move the point to the left by 4 units (-4)

For both you'll stop at -1.
