Answer:
2(x + 2)(5x-2)
Step-by-step explanation:
Here, we want to factorize the given polynomial
We have this as follows;
10x^2 + 20x - 4x -8
10x(x + 2) - 4(x + 2)
= (10x-4)(x + 2)
We can factor the first side by bringing out two and we will have;
10x-4 = 2(5x-2)
and hence;
2(x + 2)(5x-2)
2/3 because you flip 3 coins and you want to get al least 2 heads!
Answer:
b ≈ 7.8
Step-by-step explanation:
using the law of sines
∠ A = 180° - 105° - 40° = 180° - 145° = 35° , then
= 
( cross- multiply )
b × sin35° = 7 × sin40° ( divide both sides by sin35° )
b = 
≈ 7.8 ( to the nearest tenth )
Move all terms that don't contain K to the right side and solve.
K= Z/3 + 3
