If they are right triangles
Ahat [919]
You can use Pythagreos theorem to determine it!
Pythagreos theorem is a^2 + b^2 = c^2
1) 4^2 + 4^2 = 6^2
   16    +  16  = 36
         32       = 36 (So this is not a right-angled triangle )
2) 16^2 + 12^2 = 20^2
      256 + 144  = 400
       400          = 400 (Sp this is a right-ngled triangle)

Solve by factoring <br> 2x^2=19x+33
oksian1 [2.3K]

<span>2x^2 - 19x - 33 = 0 </span>

<span>The factors of 2 are 1 x 2. </span>
<span>The factors of 33 are 1 x 33 and 3 x 11. </span>

<span>Using Guess and Test and FOIL, find a combination that gives you a middle term of -19x: </span>

<span>(2x + 3)(x - 11) = 0. </span>

<span>Using the principal of zero product, solve each equation for x: </span>

<span>2x + 3 =0 and x - 11 =0. </span>

<span>The two solutions are x = -3/2 and x = 11.

The price of an item yesterday was $60. Today, the price fell to $42. Find the percentage decrease.
oksian1 [2.3K]

Answer:

-30% or 30% decrease

Step-by-step explanation:

What's percentage decrease?

  • Percent decrease is the difference between the initial value and new value, indicating a loss of value.
  • The formula to find percent decrease is \frac{NV-IV}{IV} * 100, where NV = new value and IV = initial value.

How do we solve this problem?

  • We know that the original value was $60, so that represents IV. Also, now that the price is $42, it represents NV.
  • Now, we plug in the values!
  • \frac{42-60}{60} * 100
  • \frac{-18}{60} * 100
  • -\frac{3}{10} * 100
  • -3 * 10
  • -30

Therefore, the answer is 30% decrease.
