Jason solved the following equation to find the value for
-8.5x – 3.5x = -78
x = 6.5
Describe how Jason can check his answer.

-55.25 - 22.75 = -78

Step-by-step explanation:

To check the answer, we plug the value of x into the equation;

Since x is given as 6.5, equation will be written as:

-8.5 (6.5) – 3.5 (6.5) = -78

(-8.5 x 6.5) - (3.5 x 6.5) = -78

-55.25 - 22.75 = -78

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

abde or 1,2,4, 5 is the answer
