Writing in scientific notation is writing in power form.
Writing in power form is usually in the form:
X.y × 10ⁿ
We now write 3 920 000 000 000 in this form.
3.92 × 10¹²
Answer :
3.92 × 10¹²
This is the scientific notation.
Hope I helped :)
An expression is defined as a set of numbers, variables, and mathematical operations. The simplified product of (2x+3)(x²+x-2) is (2x³+5x²-x-6).
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The simplified product of the binomial (2x+3) and the trinomial (x²+x-2) can be written as,
![(2x+3)(x^2+x-2)\\\\= (2x \times x^2)+(2x \times x) + (2x\times -2) + (3\times x^2)+(3\times x)+(3\times -2)\\\\= 2x^3 + 2x^2-4x+3x^2+3x-6\\\\= 2x^3+5x^2-x-6](https://tex.z-dn.net/?f=%282x%2B3%29%28x%5E2%2Bx-2%29%5C%5C%5C%5C%3D%20%282x%20%5Ctimes%20x%5E2%29%2B%282x%20%5Ctimes%20%20x%29%20%2B%20%282x%5Ctimes%20-2%29%20%2B%20%283%5Ctimes%20x%5E2%29%2B%283%5Ctimes%20x%29%2B%283%5Ctimes%20%20-2%29%5C%5C%5C%5C%3D%202x%5E3%20%2B%202x%5E2-4x%2B3x%5E2%2B3x-6%5C%5C%5C%5C%3D%202x%5E3%2B5x%5E2-x-6)
Thus, the simplified product of (2x+3)(x²+x-2) is (2x³+5x²-x-6).

Answer:
x=180-(67+52)
Step-by-step explanation:
a linear pair is 180
we are already have two angles add them together
subtract that from 180 and you will get the last angle
It has rotational symmetry of order 3 about the centroid of any triangle. Turning the pattern 120° gives you the same pattern.
