3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
x=-9 15 + x = 6x + 60 x = 6x + 45 -5x = 45 x = -9 15 + (-9) = (6 * (-9)) + 60 15 - 9 = -54 + 60 6 = 60 - 54 6 = 6 There is no answer because, 15+x=6x+60 -15 -15 x=6x+45 Which is imposible because "x" can't equal itself times six plus forty-five.
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
51 × 14 = 5/4 54
It is the same as 54 plus 36 and both expressions add to 90
18(2 + 3)
39x-6
9 This expression can be simplified to: 9x
It is: 18(2+3) or simply as 90
It is 3*(54n + 1.8)
If you mean 5x+4x = 54 then the value of x is 6
3(5-6) + 2 (54) -5 =105
a = 15.
(3*5)+(6 to the power of 2)+54-5
3*6*2+5+5+54=100
