A sweater is on sale for 30% off the ticketed price of $84. How much will the sweater cost after the discount?

Marianna [84]

84 x .70 = $58.80

Or if you want to do it the long way you can calculate the actual discount (your savings from this purchase first then subtract it from the original price of $84. It`s just easier to figure out what is left (which is 70% of $84).

What is one root of this equation?<br><br> 2x^-4x+9=0

Nutka1998 [239]

9514 1404 393

Answer:

1 +i√3.5

Step-by-step explanation:

In vertex form, the equation is ...

2(x² -2x +1) +7 = 0

2(x -1)² +7 = 0

Then the solutions are ...

(x -1)² = -7/2

x = 1 ±i√3.5

One solution is 1+i√3.5.
