The product of x and 2 is less than or equal to 4
MissTica
2x≤4

I'm not sure how else to help you in this situation, without you providing me with more information.  If you want the solution for x, you would just divide both sides by the coefficient of the variable, or 2, resulting in the inequality:

x ≤ 2

Hope this helps! Comment if you need to add info or have any more questions about this problem.

\text{Distribute the value of 7 in each of your terms}

\text{(2x}^3+\text{3y}^2)(7)

\text{2x}^3\times7=\text{14x}^3

\text{3y}^2\times7=\text{21y}^2

\text{We cannot combine like terms because they AREN'T any in this equation}

\boxed{\boxed{\bf{Answer:14x^3+21y^2}}}\checkmark

Which piece of additional information can be used to prove △CEA ~ △CDB?
Slav-nsk [51]

<u>Answer-</u>

<em>The correct answer is</em>

<em>∠BDC and ∠AED are right angles</em>

<u>Solution-</u>

In the ΔCEA and ΔCDB,

m\angle BCD=m\angle ACE

As this common to both of the triangle.

If ∠BDC and ∠AED are right angles, then m\angle E=90=m\angle D

Now as

∠BCD = ∠ACE and ∠BDC = ∠AED,

∠DBC and ∠EAC will be same. (as sum of 3 angles in a triangle is 180°)

Then, ΔCEA ≈ ΔCDB

Therefore, additional information can be used to prove ΔCEA ≈ ΔCDB is ∠BDC and ∠AED are right angles.
