Is your question true or false?
2abc - 3ab = -30? if a =2, b = -3 and c= 4
plug in
2(2)(-3)(4) - 3(2)(-3) = -30
Simplify
-48 + 18 = -30
-30 = -30
Both sides are equal so
It's true.
It's ASA
<C = <D
CB = DE
<B = <E
hope it helps

I have a total of 11 pencils = total outcome
a- since we have 6 Red, P(Red)=6/11
b- P(Black) = 3/11
c- P(Green) = 1/11
For the dice:
Total outcome 6 so :
P(3) =1/6
P(1) =1/6
P(less than5) means P( of 1 OR 2 OR 3 Or 4)
Since we have "OR" it means we can add the P(probabilities)====>
P( of 1 OR 2 OR 3 Or 4)=1/6+1/6+1/6+1/6=
= 4/6 = 2/3
10. angle APB = (1/2) arc AB
108 = (1/2) arc AB
multiply both sides by 2 to clear the fraction
216 = arc AB
11. Area of regular Octagon s = 5 in
A = (P * apothem)/2 => => If you divide the octagon into 8 triangles, the apothem is the perpendicular height of the triangle.
A = (5 * 8 * 6)/2
A = 120 in^2
Area of regular Hexagon s = 5 in
A = (5 * 6 * 4.3)/2
A = 129 in^2
