You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
Add 5 to -3.... then d>2 :)
An expression that represents repeated multiplication of the same factor<span> is called a </span>power<span>. The </span>number<span> 5 is called the base, and the </span>number<span> 2 is called the exponent. The exponent corresponds to the </span>number<span> of times the base is </span><span>used as a factor</span>
Answer: 25 faces
Step-by-step explanation:
Given
6 cubes are stacked over each other
Mr. Smith wants to count the number of faces
The faces which are in contact with each other are not visible to Mr. smith i.e. there will be 5 cubes with only 4 faces available and only one cube with 5 faces available, that is placed on the top.
No of visible faces
![\Rightarrow 4\times 6+1\quad \quad [\text{6 cubes with 4 faces visible+face of top cube}]\\\Rightarrow 25\ \text{faces}](https://tex.z-dn.net/?f=%5CRightarrow%204%5Ctimes%206%2B1%5Cquad%20%5Cquad%20%5B%5Ctext%7B6%20cubes%20with%204%20faces%20visible%2Bface%20of%20top%20cube%7D%5D%5C%5C%5CRightarrow%2025%5C%20%5Ctext%7Bfaces%7D)
