The expression on the left side of an equation is shown below. 3x+9= if the equation has no solution, which expression can be written in the box on the other side of the equation?

3*x

Step-by-step explanation:

Note that 3*x + 9 = 3*x if you choose to put the expression 3*x on the right side of the expression.

To solve this equation, you subtract 3 * x on both sides of the equation, obtaining:

3*x+9-3*x=3*x-3*x

9=0

You get 9 = 0. This expression cannot be true regardless of the value taken by x. You can tell then that in this case the equation has no solution.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
