Jensen wants to hang a mirror in his boat and put a frame around it. The mirror and frame must have an area of 19.75 square feet
Ber [7]
The third choice, 4x²+18x+0.25=0, is correct.

The frame will have the same thickness on both sides of the mirror.  Therefore we add 5+x+x to get the total length, and we have 4+x+x to get the total width. 

The area is found by multiplying the total width and total length:

A=(5+x+x)(4+x+x)
A=(5+2x)(4+2x)

Multiplying the binomials, we have:
A=5*4+5*2x+2x*4+2x*2x
A=20+10x+8x+4x²
A=20+18x+4x²

We know that the area is 19.75:
19.75=20+18x+4x²

We need quadratics set equal to 0, so subtract 19.75 from each side:
19.75-19.75 = 20+18x+4x²-19.75
0=0.25+18x+4x²


In standard form, it will be:
4x²+18x+0.25=0

Aiden has a gross income of $63,000 and takes the standard deduction.
Digiron [165]

a) Aiden's taxable income is $50,450.

The taxable income is equal to the gross income minus the standard deduction.

= $50,450 ($63,000 - $12,550).

b) Aiden's marginal tax rate = 22% (for taxable income falling under the income bracket of $40,526 to $86,375 for the tax 2021 year.  It is assumed that Aiden is single.

c) Aiden's effective tax rate = 13.72%.  The effective tax rate = total taxes due divided by Aiden's taxable income.

= 13.72% ($6,922/$50,450 x 100)

OR 17/100, the denominator means what place it is in. The denominator is100, so it's in the hundredth place. 0.17
