1.) There are 6 numbers you can roll on a standard dice: 1, 2, 3, 4, 5, 6
There are 3 odd and 3 even. Keep in mind that an odd plus an odd will always be even and an even plus an even will always equal an even. Only if you add an odd and an even will you get an odd.

The chances of getting an even sum are much higher which is why you should choose even.

3.) The formula for finding the area of an equilateral triangle is (<span>√3)/4(a^2) where a is just a side length.

Because the perimeter is 12 and each side of an equilateral triangle is equal, we can divide 12 by 3 sides and get each side is 4. Plug in 4 for a.

</span>(√3)/4(4^2) = (√3)/4(16)

Because (√3)/4 = (1 x √3)/4, 
 (√3)/4(16) is equal to (16 x √3)/4

You have to divide (16 x √3) by 4. 16/4 = 4, and you only need to divide once to.  We get 4√3 as the final answer.

How would i solve this
Ivahew [28]

#1

\\ \sf\longmapsto f(-3)

\\ \sf\longmapsto -(-3)^2=-9

#2

\\ \sf\longmapsto f(-5)

\\ \sf\longmapsto 5(-5)-2=-25-2=-27

#3

\\ \sf\longmapsto f(-6)=5(-6)-2=-30-2=-32

Area = πr². So you have the diameter which is 56 millimeters. And the radius (r) is half the diameter, so the radius would be 28 mm. Square 28 would be 784, multiplied by π would equal 2463.00864mm. Rounded to the nearest hundredth would be 2843.01mm².
