Answer: Sorry I don't know the answer but I recommend an app that will help you is called Mathpapa is really helpful and have helped me get A on test and homework
Step-by-step explanation: is htis one https://www.mathpapa.com/algebra-calculator.html
Step-by-step explanation:
1.
4(3x + 2) = 4(2x + 3) + 4x do the multiplying
2.
12x + 8 = 8x + 12 + 4x export like terms to the same side of the equation and add/subtract like terms
3.
12x - 12x = 4
4.
0 = 4 this is not an equation so there's no solution to this one equation
1.
10(x + 4) - 3 = 14x + 1 do the multiplying
2.
10x + 40 - 3 = 14x + 1 export like terms to the same side of the equation and add/subtract like terms
3.
36 = 4x
9 = x there's one solution to this equation
1.
1/2 (10x + 15) - 3/2 = 2x + 6 + 3x do the multiplying
2.
(10x + 15)/2 - 3/2 = 5x + 6 export like terms to the same side of the equation and add/subtract like terms
3.
(10x + 12)/2 = 5x + 6 multiply both sides with 2 so we can get rid of fraction
10x + 12 = 10x + 12
0 = 0 there's infinetly many solutions to this equation meaning whatever number written instead of x there will a solution.
Well for one, the floor and the ceiling do not need wallpaper. So you would only find the surface area each side. (48, 48, 80, 80) Then you would add all four together. (256ft squared)
The answer is 'C.'
<span>When you multiply a positive integer by a positive integer then the result must be a Positive Integer.
Hope this helps!

Tina should make 31 inch tall model to replicate 155 feet tall monument.
Step-by-step explanation:
This problem can be solved by direct unitary methods easily-
Firstly, Scale is the ratio of the dimension of the original substance to the dimension of a model
Scale= original dimension/ model dimension
Model is the miniaturised representation of a substance.
The monument is 155 feet tall
Tina replicates it with a scale 1inch: 5 feet
Thus, this means that Tina would need 155*1/5 = 31 inch tall model to replicate the complete length of the monument.
Hence Tina needs to make 31-inch tall model.
