3x + 2 8x - 1 Which simplified expression represents the perimeter of this rectangle? 2(8x - 1) + 2(3x + 2) 11x + 1 (8x - 1)(3x + 2) 22x + 2 This is a square. What is its area? P = 60 m Type the value in the box. m2 12x - 9 4x - 1 7x + 8 The perimeter of this triangle is 90 cm. How long is its hypotenuse? cm A certain number is increased by 6 then doubled. Which expression represents this situation? n + 2 × 6 2n + 6 2(n + 6) 12n n ÷ 2 + 6 A certain number is doubled then increased by 6. Which expression represents this situation? 2(n + 6) 2n + 6n 2n + 6 Double Tony's age is 12 less than triple Paulie's age. Which equation correctly represents this situation? 2T + 3P = 12 3P - 2T = 12 T - P = 12 2T - 3P = 12 The sum of two consecutive numbers is 267. Which equation represents this situation? n + 1 = 267 n + (n + 1) = 267 2n = 267 n + n + 2 = 267 The product of two consecutive numbers is 870. Which equation represents this situation? n2 = 870 n + 1 = 870 n(n + 1) = 870 n × n + 1= 870 |
