The length of a rectangle is 2 more than twice the width. Find the dimensions of the rectangle if the perimeter is 76. If x represents the width of the rectangle, then which expression represents the perimeter? 2x + 2 4x + 4 6x + 4 User: Score: Evaluate 7(-4) - |-6| + |4| 13 -18 -30
Weegy: the Answer is negative 30 User: Score: Evaluate 15÷3·(-2) + |-10| 0 15/2 -20 Weegy: the answer is 7.5 User: Evaluate 2A - 3B for A = 7 and B = -2. 20 9 8 Weegy: 2A - 3B (for A = 7 and B = -2): 2(7) - 3(-2) = 14 - (-6) = 20 User: On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid \$12.25, how many adults and children went? Which of the following equations could not be used to solve the problem? 50x + 25(30 - x) = 1225 50(30 - x) + 25x = 1225 25x + 50x = 30(1225) Weegy: The last equation could not be used. User: Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has \$3.40 in all, how many nickels, dimes, and quarters does she have? If n represents the number of nickels Janet has, which of the following equations could be used to solve the problem? 5n + 10n + 25n = 340 n + 3n + 2n = 340 5n + 30n + 50n = 340 Weegy: 5n + 10n + 25n = 340 User: If x = -3, then x 2-7x + 10 equals 22 37 40 (More)

If x = -3,
x^2 - 7x + 10
= (-3)^2 - 7(-3) + 10
= 9 + 21 + 10
= 30 + 10
= 40
