Answer:
14x+6z
Step-by-step explanation:
distribute 2 into (4x-3z) and 3 into (2x+4z)
8x-6z+6x+12z
combine like terms
8x+6x=14x
12z-6z=6z
14x+6z
hope this helps
Add in Morse code is :
.—..-..
There are 8 total symbols, 5 of them are dots.
The fraction would be 5/8 are dots.
Answer: The shorter tour is not possible.
Step-by-step explanation: For this problem, we dont even need to find R and S because we have a lot of information already given to us. On the way up, the boat travels at 25/2mph which translates to 12.5mph. On the way down, the boat travels at 25/1.25mph which translates to 20mph. Since the tour is 20 miles, we can calculate the amount of time that the tour will take. Time up:20/1,25=1.6 hours. Time down:20/20= 1 hour. When we add those up, we get 2.6 hours which is more than the desired 2.5 hours. That is why the shorter tour is not an option.
Because people enjoy it. As of now, we’re quarantining so there’s not much else to do, yk?
1. What is the simplified form of (x – 2)(2x +3)? Use the Distributive Property.
= (x)(2x) + (3)(x) - (2)(2x) - (2)(3)
= 2x^2 + 3x - 4x - 6
= 2x^2 - x - 6
Answer
2x^2 - x – 6
2. What is the simplified form of (3x + 2)(4x – 3)? Use a table.
| 3x 2
--------|-----------------------------------------
4x | 12x^2 8x
--------|---------------------------------------------
-3 | -9x -6
---------------------------------------------------------Add
12x^2 + 8x - 9x - 6
= 12x^2 -x - 6
Answer
12x^2 – x – 6
3. What is the simplified form of (4p – 2)(p – 4)?
(4p – 2)(p – 4)
= (4p)(p) - (4p)(4) - (2)(p) - (2)(-4)
=4p^2 - 16p - 2p + 8
= 4p^2 - 18p + 8
Answer
4p^2 – 18p + 8
4. The radius of a cylinder is 3x – 2 cm. The height of the cylinder is x + 3 cm. What is the surface area of the cylinder? Use the formula A = 2r2 + 2rh.
A = 2r2 + 2rh
A = 2( 3x – 2)^2 + 2 (3x – 2)(x + 3 )
A = 2(9x^2 - 12x + 4) + 2(3x^2 + 7x - 6)
A = 18x^2 - 24x + 8 + 6x^2 + 14x - 12
A = 24x^2 - 10x - 4
Answer
A = 24x^2 - 10x - 4
