Maricella’s strategy is incorrect as the values added on the left and right side of the equation changes the original equation 4x-2(3x-4)+4=-x+3(x+1)+1 to 4x-2(3x-4)+4=-x+3(x+1)+3 .

Further explanation:

Maricella begin by adding -4+4 on the left side of the equation and 1+1 on the right side of the equation 4x-2(3x-4)+4=-x+3(x+1)+1 .

The value added on the left is equal to zero so it does not change the equation but the value added on the right is 2, a non-zero digit so it changes the equation as shown below.

$4x-2(3x-4)+4-4+4=-x+3(x+1)+1+1+1\\4x-2(3x-4)+4+0=-x+3(x+1)+1+2\\4x-2(3x-4)+4=-x+3(x+1)+3$

Therefore, the strategy used by Maricella will change the equation and so the solution of the equation will be incorrect.

One way of solving such a linear equation is by adding or subtracting the required value on each side of the equation. and then simplifying the further equation.

Similarly, the other way to solve any linear equation is by separating the variable terms on one side of the equation and constant terms on the other side of the equation.

After this simplify the linear equation to obtain the solution of the equation for .

Whereas Maricella’s strategy fails to solve the equation 4x-2(3x-4)+4=-x+3(x+1)+1 since the values added and subtracted in the equation changes the original equation completely.

Answer from: Quest

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

$\frac{ab}{bc} =\frac{ad}{ab}$

now, we can cross multiply

and we get

$ab\timesab=ad\times bc$

$ab^2=ad\times bc$

so, this could be step to prove it
