Sanjay solved the equation below. which property did he use to determine that 7x + 42 = 42 is equivalent to 7x = 0?

For this case we have the following expression:

From here, we must clear the value of x.

For this, we apply the following property :

We have then:

he used Substraction property of equality

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

step-by-step explanation:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.
