The answer is <span>10 was added to each side.
</span>
<span>x² + 8x + 60 = x² + 12x + 20
____
Subtract x</span>² from both sides:

x² + 8x + 60 - x² = x² + 12x + 20 - x²
8x + 60 = 12x + 20
60 - 20 = 12x - 8x
40 = 4x
x = 40/4
x = 10

So, 10 was added to each side.

So you are given a recursive series, which is an equation that writes itself. Now we want to create a explicit rule. Explicit rule is a pattern that uses our first term and add our common difference. So it gives us our first term. a_{1}  = -3

Lets find the second term of the recursive series. 

a_2 = -3 +7 = 4

So it is increasing by 7

So our explicit rule is:

a_n = -3 + 7(n-1)

XLiV represents 64 true ya false​
V125BC [204]

Answer:

False

Step-by-step explanation:

Given

XLIV = 64

Required

True or False

The above numeral can be split as follows:

XLIV = XL + IV

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

XL = -10 + 50

XL = 40

In Roman numerals;

IV = 4

Substitute 40 for XL and 4 for IV.

XLIV = 40 + 4

XLIV = 44

Hence;

<em />XLIV = 64<em> is false</em>
