Answer:
c) 1
Step-by-step explanation:
=> ax+y = 5
<u><em>Putting x =2, y =3</em></u>
=> a(2)+3 = 5
=> 2a = 5-3
=> 2a = 2
<em>Dividing both sides by 2</em>
=> a = 1
Abd is a right angled triangle so by pythagoras we know
and to calculate h we need to use the sine rule
i hope this helps
Answer:
p= 2
Step-by-step explanation:
So first you want to distribute the 6 to 3p-2 which basically means multiply
6(3p – 2) = 24
6 times 3p is 18 and 6 time -2 is -12
* remember a negative and a positive equal a negative*
18p-12=24
you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36
18p = 36
since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2
so p = 2
if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it was like 18 + p you can subtract because 18 and p arent together
