Answer:
The equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
Step-by-step explanation:
The equation that can be use to determine the price of a sandwich is as follows:
Let us assume the price of a sandwich be x
So,
The equation would be
5x + $1.25 = $38.75
5x = $38.75 - $1.25
x = $37.5 ÷ 5
x = $7.5
hence, the equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
The possible dimensions of the prism will be evaluated as follows:
<span>60x3 + 145x2 + 70x
factoring out
factoring out 5x we get:
5x(12x^2+29x+14)
factoring the quadratic we get:
5x(3x+2)(4x+7)
hence the dimensions are:
5x by (3x+2) by (4x+7)</span>
The answer is 81
A number squared means you multiply by itself 9*9=81
Answer: 
Step-by-step explanation:
Given
The length of the rectangular prism is 
width of the rectangular prism is 
height of the rectangular prism is 
The surface area of the rectangular prism is ![2[wl+lh+hw]](https://tex.z-dn.net/?f=2%5Bwl%2Blh%2Bhw%5D)
Put the values
![\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2](https://tex.z-dn.net/?f=%5CRightarrow%202%5B8%5Ctimes%2012%2B15%5Ctimes%2012%2B15%5Ctimes%208%5D%5C%5C%5CRightarrow%202%5B96%2B180%2B120%5D%3D2%5Ctimes%20396%5C%5C%5CRightarrow%20792%5C%20m%5E2)
