If two lines intersect, then there are two possibilities
A) The lines intersect at exactly one point. This happens if the slopes of the two lines are different (the y intercepts may or may not be the same).
B) The lines intersect at infinitely many points. This happens when both slopes are the same and when both y intercepts are the same. In short, the two equations are identical. Often they may be written in different forms. For example, the equation y = 2x+1 and 2y = 4x+2 are the same equation. Divide everything in equation (2) by 2 and you'll get equation (1).

Answer:
<em>B + 21</em>
or
<em>21 + B</em>
Step-by-step explanation:
<em>The sum of B and 21 </em>
<u>The sum of</u> : means to add B and 21
The algebraic expression would be: B + 21 or 21 + B (depending on how you/your teacher wishes it to be written)
Answer:
I think the answer for the first one would be 32^2 meters for 4m × 4m and 13m. The 6m and 8m would be 48^2 meters. The second one would be 5in × 5in would be 25in and 2in × 4in would be 8in. The third one would be 6ft × 6ft × 6ft would be 48ft.
Step-by-step explanation:
To find area, you have to multiply the sides of each figure.
- A = a^2 = 4m × 4m × 13m = 32.
- A = a^2 = 6m × 8m = 48.
- 5 × 5 = 25.
- 2 × 4 = 8.
- 6 × 6 = 36 + 12 = 48.
I hope this helps your question!
