If 2x^2+2x=12, what is x?

Rainbow [258]

Answer:

x= 2

x= -3

Step-by-step explanation:

<u>Solving as normal quadratic equation:</u>

2x^2+2x=12
x^2 +x = 6
x^2 + x - 6= 0
x = (-1 ± √(1+4*1*6)/2
x = ( - 1 ± √25)/2
x = (-1 ± 5)/2
x= 2
x= -3

<u>Roots are</u> 2 and -3

Which equation can be used to calculate the surface area of the rectangular prism net shown below?

Bess [88]

Answer:

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

Step-by-step explanation:

we know that

The surface area is equal to the area of all the faces of the triangular prism

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

simplify

$SA=(5)(12)+(5)(10)+(12)(10)+(13)(10)$

$SA=360\ cm^{2}$
