do we have to simplify it or expand it coze it is already simplified
2x - 5y = 11. (4, a). x = 4, y = a
Substituting into 2x - 5y = 11
2(4) - 5(a) = 11
8 - 5a = 11
-5a = 11 - 8
-5a = 3
a = 3/-5 = -3/5 =- 0.6
Other coordinate = -3/5 = -0.6
You can always try 4 divide 2/3=
and what ever you get is your answer
4 divide 2/3= 0.66666666666
Your going to have to round
Hope this helps

Step-by-step explanation:
Use pythagorean theorem
Answer:
a. 10√2
Step-by-step explanation:
hey, just use Pythagoras theorem
h²=p²+b²=10²+10²=100+100=200
h²=200, h= √200 =√(100×2)=√100×√2=10√2
