It is -8x.

-2x + 4 < 10 -4 -4 --------------------- -2x < 10 --- ---- (divide) -2x -2x ---------------- -x > -5 (switch the sign when you divide by a negative) Hope that helps :)
log(2) + log(4) = log(2x)log(2 times 4) = log(2x)2 times 4 = 2 times 'x'x = 4
-64 : 2x(-16) = 2
No. If x = -2, then y = -(2x) -(+6) = -2*(-2) - 6 = +4 - 6 = -2
It is: -2x squared

2x * 2x (2*2=4) therefore, 2x*2x equals 4x2.

log(2) + log(4) = log(2x)log(2 times 4) = log(2x)2 times 4 = 2 times 'x'x = 4
(3x+1)(2x+4) = 6x2+4+2x+12x = 6x2+14x+4
-64 : 2x(-16) = 2
No. If x = -2, then y = -(2x) -(+6) = -2*(-2) - 6 = +4 - 6 = -2
x= Negative 4
To multiply (2x^2) by (2x^2), you multiply the coefficients and the variables separately. The coefficients (2 \times 2) equal (4), and for the variables (x^2 \times x^2), you add the exponents, resulting in (x^{2+2} = x^4). Therefore, (2x^2 \times 2x^2 = 4x^4).
2X - 4 = -10 2X = -6 X = -3
