At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual.

Answer

The tool set costs $68 during the sale this week.

Explanation

We know that...

Normally the tool set costs $80.

During the sale, the tool set costs $12 less than usual.

So you should subtract to find the cost of the tool set during the sale.

80-12=68

So the tool set would cost $68 during the sale.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
