(a+3)(a-2)
(a² -2a +3a - 6) =0
(a² + a - 6 ) = 0
Use splitting the middle term
a² + 3a - 2a - 6 = 0
a(a+3) - 2(a+3) = 0
(a-2)(a+3) = 0
Values of a are
a - 2 = 0
a = 2 .....(i)
a+3 = 0
a = -3 .....(ii)
Answer:
15u + 141 = 420
Step-by-step explanation:
So basically we are modelling how much the coach is spending. Each player is given a uniform and a basketball
We can use 'u' as the cost of a single uniform
We can use 'b' as the cost of a single basketball
Since there is 15 players we must give a ball and uniform to each so
15u + 15b = 420
The problem gives us the cost of each basketball: 9.40
so now 15u + 15(9.4) = 420
15u + 141 = 420
They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
