Answer:
4(R + 5 + R + 2) [Option B]
Step-by-step explanation:
<u>GIVEN :-</u>
- Length = R + 5
- Width = R + 2
<u>TO FIND :-</u>
- Perimeter of the rectangle
<u>FORMULAE TO BE USED :-</u>
For a rectangle with length 'l' and width 'w' , its perimeter = 4(l + w)
<u>SOLUTION :-</u>
Perimeter = 
= 
= 
Hello!
As you can see, 3x+9 makes a right angle, or 90 degrees. We can turn this into an equation and solve for x.
3x+9=90
First we subtract 9 from both sides.
3x=81
Then divide both sides by 3.
x=27
Therefore, x=27.
I hope this helps!

Y = tan (√ t )
We will use chain rule.
( tan x ) ` = sec² x
( √ t ) ` = 1 / 2√t
y ` = sec² (√ t ) · 1 / 2√t
y` = 1/cos² ( √ t ) · 1 / 2√t
Okay so truck a holds x and truck b holds y. truck a makes 12 trips and truck b makes 14
each time the deliver x or y amount
so say the amount needed at the site is z
truck a has the equation 12x=z
truck b has the equation 14y=z
so 12x=14y and dividing yields 12/14x=y
so that means 6/7x=y
so y can only hold 6/7 of what x can hold.
not sure about expression that represents difference wording. but this should get you off to a good start ;)
