MPM1D - polynomials intro

What is the correct expression that represents the perimeter of this right triangle? 30x 30x ^{3}30x ^{2}30 13x 12x 5x What is the correct statement given the set of terms: {6x, -9x, 4x and -10x}? These terms cannot be added as some have different signs These terms are all "binomials" as they each have two parts Since two terms are negative and two are positive, when added the result is zero. These terms, when added, have a sum of -9x. Given this rectangle, what is the simplified expression for its perimeter? 4w - 6 8w - 12 8w + 12 8w ^{2} - 123w - 12 w + 6 For his pay, Ahmad earns $125 plus $25 for every car he sells. The expression for his pay is: 125 + 25x 150x 125 - 25x 125x + 25 This is a trinomial whose coefficients are {+3, +2 and -10} This expression can be evaluated right now. Given the expression: 3x ^{3} + 2x^{2}y - 10xy, which statement is correct? This is a trinomial with two "like" terms. The fully simplified expression is -5x ^{6}y^{2}If the binomial 7x - 11y is multiplied by 5 (added to itself five times), it simplifies to become: 12x - 6y 12x - 16y 35x - 55y 7x - 11y X 5 Given this diagram, what is the simplified expression that represents just the shaded area?108x 34x ^{2}11x 5x68x 2x54x ^{2}4x |
