Multiply.
(v+3)(v-8)
simplify your answer.

v² -5v -24

Step-by-step explanation:

(v +3)(v - 8)

FOIL

Front

v x v = v²

Outer

v x -8 = -8v

Inner

3 x v = 3v

Last

3 x -8=-24

put it together in standard form (highest exponent to lowest)

v² - 8v +3v -24

combine like terms

v² -5v -24

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
