Solve the equation X^2+4X-10=0 to the nearest tenth.

x = 5.7

Step-by-step explanation:

Add 10 to both sides of the equation. x 2 − 4 x = 10 To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b . ( b 2 ) 2 = ( − 2 ) 2 Add the term to each side of the equation. x 2 − 4 x + ( − 2 ) 2 = 10 + ( − 2 ) 2 Simplify the equation. Tap for more steps... x 2 − 4 x + 4 = 14 Factor the perfect trinomial square into ( x − 2 ) 2 . ( x − 2 ) 2 = 14 Solve the equation for x . Tap for more steps... x = ± √ 14 + 2 The result can be shown in multiple forms. Exact Form: x = ± √ 14 + 2 Decimal Form: x = 5.74165738 … , − 1.74165738 …

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
