Add a percent sign
Question one is y( Insert sign) -9
ITS 100 trAilmix be because you multiply 25 Times 1/8 and multiply the answer OF 25 Times 1/8 in 25
-3√45 + 3√20 = -3√(9 · 5) + 3√(4 · 5) =
= -3√(3² · 5) + 3√(2² · 5) =
= -3 · 3√5 + 3 · 2√5 =
= -9√5 + 6√5 = -3√5 ← the end
I think it’s 34 hope this helps
