Answer:
lj= lk din 30 give lj= 4✓2
and ml=x= lj cos 45
on solving x= 4✓2 cos45=4
Yes, he is correct, using the distributive property you get the same answer
Answer:
Step 1: Transpose everything to one side
12. x²+16x+15-10x+4=0
Step 2: Add the like terms
x² + (16x - 10x) + 15 + 4=0
x² + 6x + 19=0
Step 3: Use the quadratic formula to get the value(s) of x.
a=1 b=6 c=19

therefore, x=... or x
