-8x - 11x<br> I really need help
Tema [17]

Answer: -19x

Step-by-step explanation: In this problem, we're asked to simplify the expression.

The two parts of this expression, -8x and 11x are called terms. The numbers in front of the variables are called coefficients.

Because the variables, x and x are identical, the terms get a special name and they're called like terms.

To subtract like terms, we simply subtract their coefficients and add the variable on to the difference of the two numbers.

Since -8 (-11) is -19, -8x - 11x simplifies to -19x.

Help w this plsss,!,!,, 20pointsss
Kay [80]

Answer:

Area = Length × width

16 = (3x +2 ) × ( x)

16 = 3x² +2x

3x² +2x -16=0

( 3x+8 ) ( x -2 ) =0

3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6

x-2=0 —> x = 2

I hope I helped you^_^
