Answer:
3x + 4
Step-by-step explanation:
4x + 3 - (x-1)
expand the bracket
=4x + 3 - x + 1
=4x - x +3 + 1
=3x + 4
Answer:
7x + 14y + 2
Step-by-step explanation:
(3x+8y+8)+(4x+6y-6)
3x + 8y + 8 + 4x + 6y - 6
3x + 4x + 8y + 6y + 8 - 6
7x + 14y + 2
Answer:
Step-by-step explanation:
Given that rectangle has side length 23x13 feet.
When squares of side x are cut from all the four sides we have dimensions as
23-2x and 13-2x and height x
Volume 

Use derivative test
First derivative V'(x) 
Equate I derivative to 0
We get approximate value of x = 2.671, 9.329
Since width is 13 feet it cannot be 9.329
Hence x = 2.671
V"(x) = -80 <0
So maximum volume is

Answer:
f(x)=3 x (4)^x
Im pretty sure the answer is A.
