15a - 54 = -9. Add 54 to each side.

15a = 45. Divide each side by 15.

a = 3

Simplify the expression.<br> 16n−16
Alex787 [66]

Answer:

16(n-1)

Step-by-step explanation:

16(n-1) is the simplest form of 16n-16 because you cannot backtrack any farther. To get to 16n-16, you must have 16(n-1) first. When you distribute, you will have 16n and -16. Put those into an equation, you get 16n-16 which is what you have originally.

FIND sin0 WHERE 0 IS THE ANGLE SHOWN. GIVE AN EXACT VALUE, NOT A DECIMAL APPROXIMATION. Branliest​
expeople1 [14]

Answer:

\frac{\sqrt{15} }{8}

Step-by-step explanation:

We require to find the third side of the triangle.

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x represent the third side, then

x² + 7² = 8², that is

x² + 49 = 64 ( subtract 49 from both sides )

x² = 15 ( take the square root of both sides )

x = \sqrt{15}

Thus

sinΘ = \frac{opposite}{hypotenuse} = \frac{\sqrt{15} }{8}
