It is 123.99
(x+3)(x+4) = x²+7x+12
4x + 4 or 4(x + 1)
(x + 3)(x + 4) = x2 + 7x + 12
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
(x+3)(x+4)=x2+7x+12
(x+3)(x+4) = x2+7x+12
It is: (-10)+(-3)+4 = -9
3 + 4 + 4 x 15 = 67
12
119.96 + 4 + 3 + 576 + 4 + 3 + 4.5 = 714.46
X + X + X + X = 4x It is the same as 4 x X = 4x Think numbers . 3 + 3 + 3 + 3 = 12 = 4(3) or 4 x 3 = 12 = 4(3) In mathematics instead of writing a 'string of plusses(+), it is easier to write the number of plusses multiplied to the given number.
