Answer:
Zero Property.
Step-by-step explanation:
The Zero property states that in an equation of:
ab = 0
Either a or b, or both, must be zero to obtain a result of 0.

Answer:
x=-5
Step-by-step explanation:
When finding x, we basically have to isolate the variable. By isolating the variable, usually doing the opposite operation helps it.
Addition is the opposite of Subtraction
Multiplication is the opposite of Division
Let's dive into this problem!
x+7=2
(we need to isolate x. basically we need to get rid of this 7. How do we do this? since it is added by seven, we can subtract it by both sides to get rid of it on the x side.)
x+7=2
-7 -7
x=-5
(subtract 2-(-5), this adds to -5)
This is your final answer.
We want to list the steps involved in multiplying fractions;
Taking an example;

First steps are;
- Multiply the numerators together
- Multiply the Denominators together

Next is to;
Check to see if the product can be simplified;

So, we get the product to be;
Answer:
Marcela tardó 6 horas y Roberto tardó 8 horas.
Step-by-step explanation:
Dado que Marcela tardó dos horas menos que Roberto en recorrer una distancia en bicicleta, y sabiendo que el producto de los dos tiempos es de 48 horas, para determinar cuánto tardó cada uno se debe realizar el siguiente cálculo:
M = X
R = X + 2
X x (X + 2) = 48
8 x 6 = 48
Por lo tanto, Marcela tardó 6 horas y Roberto tardó 8 horas.
Option A: >
Solution:
Given a triangle GHJ.
The line GH is perpendicular to line HJ.
This means the triangle is a right angled triangle.
In ΔGHJ, GH is the base of the triangle and
HJ is a height of the triangle.
Then the third side must be the hypotenuse of the right triangle.
We know that by the Pythagoras theorem,


This clearly shows that the hypotenuse is greater than the height.
⇒ GJ > HJ
Option A: > is the correct answer.
If line GH is perpendicular to line HJ, then GJ is > HJ.
