Anastasy [175]

Answer:

$\boxed{\sf \ \ \ x = -8 \ or \ x = -4 \ \ \ }$

Step-by-step explanation:

Hello,

$4x^2+48x+128=0\\ 4(x^2+12x+32)=0\\ x^2+12x+32=0\\ (x+6)^2 - 36 + 32= 0\\\\ (x+6)^2-4=0\\ (x+6+2)(x+6-2)=0\\ (x+8)(x+4) = 0\\ x = -8 \ or \ x = -4$

Help meeeeeeeeeeeeeeeee

lys-0071 [83]

I think it's just determining what the negative means. Negative with the x axis means to the left (because the left side is negative). Negative with the y axis is down (because the down side is negative.) So once you know that, it's obviously D because both are negative.

I hope that helped!

Help me find the surface area of a triangular prism with work please

Leokris [45]

The diagram shows how the surface area can be "flattened" into two rectangles, one for the end triangles that is 6 cm by 5.3 cm, and one for the lateral area that is 13 cm by 19.3 cm.

The total area is
.. (6 cm)*(5.3 cm) +(13 cm)*(19.3 cm)
.. = 31.8 cm^2 +250.9 cm^2
.. = 282.7 cm^2
