The average temperature of kopikoville was reported to be - 20° last year. this year, the average temperature of kopikoville rose by 6°. which of the following is true about this year's average temperature of kopikoville? a. this year's average temperature of kopikoville is 26°. b. this year's average temperature of kopikoville is 14°. c. this year's average temperature of kopikoville is - 26°. d. this year's average temperature of kopikoville is - 14°.

- 14

Step-by-step explanation:

This is a place I sure don't want to live in. The summer probably has all sorts of disagreeable insects like mosquitoes and horseflies.

If the average temperature rose by 6 degrees then just add 6 onto - 20

- 20 + 6 = - 14

Note that rose means add. Think money. If you owe someone 20 dollars your net value is - 20. You could say your debt is 20.

If you cut someone's grass and they give you 6 dollars, then your net worth is - 20 + 6 = - 14. You still owe money. Just not as much.

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
