Write the following expression in expanded form: 53 (1 point) Responses 5 x 3 5 x 3 3 x 3 x 3 x 3 x 3 3 x 3 x 3 x 3 x 3 3 x 5 3 x 5 5 x 5 x 5
5 x 3 = 15
Evaluate the following expression when x = 5: 8(2x+6)(1 point) Responses 86 86 24 24 104 104 128
When x = 5,
8(2x+6) = 8(2(5)+6) = 8(10+6) = 8(16) = 128
Evaluate the following expression: 3x+6ā5 when x = 2(1 point) Responses 10 10 7 7 6 6 4 4
When x = 2,
3x + 6 - 5 = 3(2) + 6 - 5 = 6 + 6 - 5 = 12 - 5 = 7
Evaluate the following expression: 5cā2k when c = 7 and k = 3(1 point) Responses 7 7 29 29 3 3 34
When c = 7 and k = 3,
5c - 2k = 5(7) - 2(3) = 35 - 6 = 29
Evaluate the following expression: 4c+72ār+2w when w = 3, c = 5, and r = 11(1 point) Responses 64 64 29 29 106 106 21 21
When w = 3, c = 5, and r = 11,
4c + 72 - r + 2w = 4(5) + 72 - 11 + 2(3) = 20 + 72 - 11 + 6 = 98 - 11 + 6 = 87 + 6 = 93
