Last year my parents had a combined income of 56,000 They paid 13,600 in federal income taxes. What simplified fraction shows ho

koban [17]

Answer:

$\frac{17}{70}$

Step-by-step explanation:

From the information given, you know that your parents paid $13,600 in taxes from their income that was $56,000. The fraction would be:

$\frac{13600}{56000}$

To simplify this, first you can eliminate two zeros at the end of each number:

$\frac{136}{560}$

Now, you can divide both numbers by 8, which will result in:

$\frac{17}{70}$

According to this, the simplified fraction that shows how much your parents spent on their federal taxes is $\frac{17}{70}$ .

What is the value of x given that figure ADCB

aleksley [76]

Answer:

Step-by-step explanation:

Because the trapezoid is isosceles, the two diagonals are congruent. This can be shown by ASA.

ACD = BDC Properties of parallel lines.

DC = DC A line is equal to itself

DBA = CAB Property of parallel lines.

AC = DB Parts of Congruent triangles are congruent

3x + 15 = 7x - 9 Add 9 to both sides

3x + 15 + 9 = 7x

3x + 24 = 7x Subtract 3x from both sides.

24 = 7x - 3x

24 = 4x Divide by 4

24/4 = 4x/4

x = 6

Factorise a.x3+4.a.x

Contact [7]

Answer:

${ax}^{3} + 4ax \\$

factorise out a and x :

${ \boxed{answer{= ax( {x}^{2} + 4) }}}\\ but \: farther \: more : \\ = ax( {x}^{2} + {2}^{2} )$

but from general factorization:

${ \boxed{( {a}^{2} + {b}^{2}) = {(a + b)}^{2} - 2ab }}$

a » x

b » 2

therefore:

$= ax \{ {(x + 2)}^{2} - 2(x)(2) \} \\ \\ = { \boxed{ \boxed{ax( {x + 2)}^{2} - 4x }}}$
