Answer:12
Step-by-step explanation:
Hi!
A perfect square is the product of when a whole number is multiplied by itself
Ex:
6 × 6 = 36, 36 is the perfect square.
The number that is being multiplied is the square root.
So to find the correct answer for this question, let's use the process of elimination.
100 = 10 × 10 so we can cross out 100
64 = 8 × 8 so we can cross out 64
25 = 5 × 5 so we can cross out 25
Now all we have left is 24, which is not a perfect square.
Answer: A. 24
Hope this helps :)
Answer:
Below.
Step-by-step explanation:
y + 2 > -3(x + 1)
y + 2 > -3x - 3
y > -3x - 5
The graph will be the graph of the line y = -3x - 5 (dotted line), with the area above the line shaded.
Answer:
= - 4 cm/s
Step-by-step explanation:
Let us revise the chain rule
If = a and 
= b, then
= ÷ = 
∵ y = x² + 1
- Use the differentiation to find
∴ = 2x
∵ x = -1
- Substitute x by -1 in
∴ = 2(-1)
∴ = -2
∵ = ×
∵ = 2 cm/s
∴ = (-2) × (2)
∴ = - 4 cm/s
Formula for volume = length x height x breadth
7a) 13.5 x 3.5 x 11.5 = 543.375
7b) 24 x 10 x 30.5 = 7320
