Answer:

78 square inches

Step-by-step explanation:

It is given that the length of the glass triangular prism for a telescope=5.5 inches, sides of the triangular prism = 4 inches and height =3 inches.

Thus, Surface area of the triangular prism =bh+(s_{1}+ s_{2}+s_{3})H where H is the length of the triangular prism.

SA=(4)(3)+(4+4+4)(5.5)

=12+12(5.5)

=78 square inches.

Alexxx [7]

Answer:

\huge\boxed{x=-\dfrac{44}{3}=-14\dfrac{2}{3}}

Step-by-step explanation:

-2x-117=10x+59\qquad|\text{add 177 to both sides and subtract}\ 10x\ \text{from both sides}\\\\-2x-10x-117+117=10x-10x+59+117\\\\-12x=176\qquad|\text{divide both sides by (-12)}\\\\\dfrac{-12x}{-12}=\dfrac{176}{-12}\\\\x=-\dfrac{176:4}{12:4}\\\\x=-\dfrac{44}{3}
