-2(-3)=6
This is because a number next to another number in a bracket indicates multiplication. Because both numbers are negative, they cancel out to become positive.

Help my homework pls!!!!!!​

Answer:

(2x^2 + x-3)/(4x^2-9)

Step-by-step explanation:

The denominator looks like an expression in which we have applied the difference of two squares to

In that case, we know that;

a^2-b^2 = (a-b)(a+ b)

That means we would be have 2x + 3 as the other denominator factor and the expression at the denominator would be;

(2x + 3)(2x-3) = 4x^2 - 9

Also, we would have to cancel out 2x + 3 from the numerator too, so as to be left with only the binomial

That means;

(2x+3)(x-1) = 2x^2-2x+ 3x - 3 = 2x^2+x -3

So we have the original expression as;

(2x^2 + x-3)/(4x^2-9)

GiveN:

  • ABCD is a parallelogram.
  • AC and BD are the diagonals.
  • DE = 28 units

To FinD:

  • Value of x in length of BE?

Step-wise-Step Explanation:

We know that,

In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. Then, AE = EC for diagonal AC and BE = DE for diagonal BD.

⇒ BE = DE

⇒ x - 4 = 28 units

⇒ x = 32 units

Hence, The required value of x here is <u>3</u><u>2</u><u> </u><u>units</u><u>.</u>

If the expression below has a positive value, which inequality represents all possible values of x in the expression
Andrei [34K]
Your answer would be “a”.

In order to receive a positive solution in the following equation, you must include a double negative to have them cancel each other out and come up with a positive value. Sorry if this is confusing it’s easier to explain this process in person rather than online but I hope this helps anyways :)
