How do you do addition and subtraction in Scientific Notatation?

1 answer:

6 0

Once the numbers have the same base and exponents, we can add or subtract their coefficients. Determine the number by which to increase the smaller exponent by so it is equal to the bigger exponent.

I hope this helps!

Answer:

Step-by-step explanation:

1) (x-3),(x-8)

2) 3x^3+3x^2=27x

3 ( x 3^3+ x ^2 − 9 x − 9 )

3 ( x ^2 ( x + 1 ) − 9 ( x + 1 ) )

3 ( ( x + 1)( x ^2 − 9 ) )

3 ( ( x + 1 ) ( x ^2 − 3 ^2 ) )

3 ( x + 1 ) ( x + 3 ) ( x − 3 )

I will mark you brainiest if you can answer this 12 - 13 x ≥38

Shtirlitz [24]

<h3>Explanation</h3>

Given Inequality

$12 - 13x \geqslant 38$

Solve the Inequality for x-term by making x as the subject.

Solving Inequality is almost the same as solving the equation.

$- 13x \geqslant 38 - 12 \\ - 13x \geqslant 26$

The problem is here. Some people might forget that when we move the negative coefficient to another side, we have to flip/swap or change the sign to opposite. That means we have to change from >= to <=

$x \leqslant \frac{26}{ - 13} \\ x \leqslant - 2$
