Answer:

\frac{9}{4}

Step-by-step explanation:

Here we will first split the middle term in such way that it is a product of 2 and some factor. In this case 3 can be splitter as product of 2 and 3/2.

We then add the square of 3/2 on both sides. Let us see how:

x^2+3x=6\\x^2+2*\frac{3}{2}*x=6\\x^2+2*\frac{3}{2}*x+(\frac{3}{2})^2=6+(\frac{3}{2})^2\\(x+\frac{3}{2})^2=6+\frac{9}{4}\\(x+\frac{3}{2})^2=\frac{33}{4}

HELP ASAP I NEED IT BADDDD !!
murzikaleks [220]

Answer:

The correct complex numbers would be, -2 - 4i and 2 + 2i

(−2 − 4i) − (2 + 2i) = -4 - 6i

Step-by-step explanation:

(−2 − 4i) − (2 + 2i)

Subtract 2 + 2i from −2 − 4i by subtracting corresponding real and imaginary parts.

−2 − 2 + (−4 − 2)i

Subtract 2 from −2. Subtract 2 from −4.

-4 - 6i

So, the correct complex numbers would be, -2 - 4i and 2 + 2i

What is the measure of ZB?​
brilliants [131]

Answer:

∠ B = 116°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , that is

∠ B + 28° + 36° = 180°

∠ B + 64° = 180° ( subtract 64° from both sides )

∠ B = 116°
