Answer:
45 meters
Step-by-step explanation:

Okay so basically you will need two sets of working out.
Sandra:
I=PRN
=14000x7x0.045
=4410
Cindy:
I=PRN
=14000x7x0.06
=5880
5880-4410
=1470
Therefore, Cindy earnt $1470 more than Sandra after 7 years.
Answer: The side length of the pet shop sign=5/4 inches
Step-by-step explanation:
Given: Candy draws a square design with a side length of x inches for the window at the pet shop.
She takes the design to the printer and asks for a sign that has an area of
square inches.
Let y(x) =
differentiating both sides w.r.t x we get
y'(x)=32x-40
to find critical point x ,Put y'(x)=0 then
⇒32x-40=0
⇒x=5/4
Therefore the side length of the pet shop sign=5/4 inches.
Its the 2nd answer choice
Answer:
D) 2x² + x - 10
Step-by-step explanation:
First, distribute the negative sign to all terms within the second parenthesis:
- (4x - x² + 6) = -4x + x² - 6
Next, combine like terms:
5x + x² - 4 - 4x + x² - 6
(x² + x²) + (5x - 4x) + (-4 - 6)
2x² + x - 10
2x² + x - 10 , or D) is your answer.
