Step-by-step explanation:

{y}^{2}   - 1 = 80

{y}^{2}  = 81

y = ±9

\frac{y - 4}{4}  = 1

y - 4 = 4

y = 8

\frac{10 - 63}{y}  = 1

10 - 63 = y

- 53 = y

I will give Brainliest its maths and I need help on a b and c
JulsSmile [24]

Answer:

{5}^{3}  \times  {5}^{x}  =  {5}^{7}  \\ 3 + x = 7 \\ x = 4

( {q}^{2} )^{y}  =  {q}^{6}  \\ 2y = 6 \\ y = 3

{1000}^{m}  \div  {100}^{n} =  {10}^{z}   \\  \frac{1000 ^{m} }{ {100}^{n} }  =  {10}^{z}  \\   \\ {10}^{m - n}  =  {10}^{z}

Can I have the brainliest please?

What is the surface area of this right triangular prism ? round your answer to the nearest tenth.​
velikii [3]

Answer:

78 m^2 Unless I got some of the measurements wrong, kinda hard to see them.

Step-by-step explanation:

The surface area will be the sum of the area of each face.  so lets see, there is the base (in this orientation) which is a 8x3 rectangle it looks like.

then two trianglular sides with both having a base of 8 and height of 3

then two "roof" pieceswhich are rectangles again, one side of 3 and the other 5.

Now we add each face up.

rectangular base = 3x8 = 24

2 triangular sides = 2(.5*8*3) = 24

2 rectangular roof pieces = 2(5*3) = 30

Now add it all up

24+24+30 = 78
