A ∩ B is the set that contains elements common to set A and set B.
here its {10 40 60}
Answer:
90 -63=27 so the answer is 27 because complementary angles add to 90
The answer to your question is <
-3 1/2 is greater that -4.1
9x^2+t+25=(ax+b)^2
9x^2+t+25=a^2*x^2+2abx+b^2 so
a^2=9 so a=3
b^2=25 so b=5 then
t=2ab using a and b from above
t=2*3*5=30
So the missing term is 30x
2x^2+7x-5+(-8x^2-3x+5)=-6x^2+4x.
