The expression for the area of frame is 4x² + 24x + 35
<h3>What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Here, Old length of photograph = 5 inch
Old width of photograph = 7 inch
Now, length of new photograph = (5 + 2x) inch
width of new photograph = (7 + 2x) inch
Now, Area of frame with new dimension = Length X breadth
= (5+2x) X (7+2x)
= 5(7+2x) + 2x(7+2x)
= 35 + 10x + 14x + 4x²
= 4x² + 24x + 35
Thus, the expression for the area of frame is 4x² + 24x + 35.

It’s the amount I have this in my notes lemme look for it pls
Answer:
<h3>16m/s</h3>
Step-by-step explanation:
If the object travels from L to M at an average speed of 10 m/s in 6 seconds, we can get the distance LM using the formula;
Speed = Distance/Time
Distance = Speed * Time
Distance = 10 * 6
Distance = 60m
Hence LM = 60m
Since LN = LM + MN
160 = 60 + MN
MN = 160-60
MN = 100m
If the object moves from M to N at an average speed of 25 m/s througj a distance od 100m, the time taken will be expressed as;
Time = distance/speed
Time = 100/25
Time = 4secs
Total time taken to move from L to N is 6secs + 4secs = 10secs
The average speed of the object for it's entire journey from L to N will be:
Average speed = Distance LN/10
Average speed for the entire journey = 160/10 = 16m/s
Hence the average speed of the object for it's entire journey from L to N is 16m/s
