Solve the following equations : 2(x -1) + 3(x +1)=4(x+4)

1 answer:

3 0

This is how I'd work it:

2(x-1)+3(x+1)=4(x+4)
2x-2+3x+3=4x+16
5x+1=4x+16
x=15

To check, substitute x into the original equation and solve:

2(15-1)+3(15+1)=4(15+4)
28+48=76
76=76

a box has a length of 15 centimetres , a width of 22 centimetres, and a height of 9 centimetres.what is the surface area of the

zzz [600]

Answer:

1326 cm²

Step-by-step explanation:

1) Identify the equation of the surface area of a rectangular prism

$A = 2(wl + wh + hl)$

2) Input the corresponding values $l=15 cm$ ; $w=22 cm$ ; and $h=9 cm$ into the equation, and solve for the area

$A=2(wl+wh+hl)\\A=2((22)(15)+(22)(9)+(9)(15))\\A=2(330+198+135)\\A=2(663)\\A=1326 cm^{2}$

3) ∴ $A=1326cm^2$
