(m+n)-(______) =2m-p.
According to the meaning of the question, the formula is (M + n) - (2m-p), which is reduced to (M + n) - (2m-p) = m + n-2m + P = - M + N + P
(30 and 2 / 3) × (29 and 1 / 3)
Original formula = (30 + 2 / 3) × (30-2 / 3)
=30²-(2/3)²
=900-4/9
=899 and 5 / 9

In the triangle ABC, a, B and C are three sides, the square of (a + b) - the square of C = 2Ab, then the triangle is___________ triangle? How many answers should there be? I wrote right triangle or isosceles triangle or isosceles right triangle, p. I know there must be a right triangle, but I asked if it could be isosceles or isosceles right triangle? If a = B, then the original formula = 2A ^ 2 + 2A ^ 2-C ^ 2 = 2A ^ 2 That is, C ^ 2 = 2A ^ 2, according to the Pythagorean theorem, C ^ 2 = a ^ 2 + B ^ 2, then the equation holds! It may be an isosceles right triangle!
