four times the sum of some number plus 1 is equal 12 times the difference of the number and 3. Find the number
aleksklad [387]
<h3><u>The value of x is equal to 2.</u></h3>

4(x + 1) = 12(3 - x)

<em><u>Distributive property on both sides.</u></em>

4x + 4 = 36 - 12x

<em><u>Add 12x to both sides.</u></em>

16x + 4 = 36

<em><u>Subtract both sides by 4.</u></em>

16x = 32

<em><u>Divide both sides by 16.</u></em>

x = 2

Explain how to apply the laws of exponents when multiplying and dividing numbers written in scientific notation.
Jlenok [28]
It is more effective if I explain using examples. So, for multiplication, you just have to multiply the magnitude, then add the exponents of the base 10. For example, when you multiply 5.2×10³ and 1.6×10², the solution would be:

(5.2)(1.6)(10³⁺²) = 8.32×10⁵

Now, for division, you will have to divide the magnitudes, and subtract the exponents by numerator minus denominator. The solution is as follows:

(5.2/1.6)(10³⁻²) = 3.25×10¹

Simplify the expression. 3 + 4i over 2 + 4i
deff fn [24]

\dfrac{3+4i}{2+4i}=\dfrac{3+4i}{2+4i}\cdot\dfrac{2-4i}{2-4i}=\dfrac{(3)(2)+(3)(-4i)+(4i)(2)+(4i)(-4i)}{2^2-(4i)^2}\\\\=\dfrac{6-12i+8i-16i^2}{4-16i^2}=\dfrac{6-4i-16(-1)}{4-16(-1)}=\dfrac{6-4i+16}{4+16}\\\\=\dfrac{22-4i}{20}=\boxed{\dfrac{11-2i}{10}}=\boxed{\dfrac{11}{10}-\dfrac{1}{5}i}
