The quadratic is not factorable, to figure this out use this formula (b^2-4ac) to figure out the discriminant. If the discriminant comes out to be a perfect square or equal to zero then we can say it’s factorable if it does not meet those requirements it’s not. In this problem it’s 8^2-4*3*3. Simplify and you get 64-36 which is equal to 28. 28 is not a perfect square or equal to zero therefore this is not factorable. If you need the root the quadratic formula would be a good option also look on the bottom if that’s what u need.

Hope this helps!

Area of trapezoids <br>find the area​
Zinaida [17]

Answer:

Area of the trapezoid = 6cm^2

Step-by-step explanation:

Area of a trapezoid:

(1/2)*Sum of parallel opposite sides +Distance between the parallel sides

Parallel sides are: 2 cm  and 4 cm

Distance between the parallel sides is 2 cm

Area of the trapezoid:

                            =\frac{1}{2}*(2+4)*2\\\\=\frac{1}{2}* 6*2\\\\=\frac{12}{2}\\\\ =6cm^2

Area of the trapezoid is 6cm^2

Simply.<br><br> -2/5 + 4/3<br><br> Show work.
mixer [17]

Answer:

14/15

Step-by-step explanation:

Find common denominators. Note that what you do to the denominator, you do to the numerator.

Use 15 as the common denominator:

(-2/5)(3/3) = (-6/15)

(4/3)(5/5) = (20/15)

Combine like terms:

-6/15 + 20/15 = (20 - 6)/15 = 14/15

14/15 is your answer.
