Answer:
= 570
Step-by-step explanation:
Priority in order:
(50 x 40 / 4 + 20) + (50 / 2 + 25)
= (2000 / 4 + 20) + ( 25 + 25)
= ( 500 + 20) + ( 50 )
= ( 520 ) + 50
= 520 + 50
a²+b²=x²
4²+3²= x²
16+9= x²
25= x²
V25= x
5= x
3y √21 + 2 y√15
To simply, we open up the bracket
We have this as;
√(189y^2) + √60y
= 3y √21 + 2 y√15
10/15x-3/15x=x-1
7/15x=x-1
x=7/15x+1
8/15x=1
x=15/8
