Answer:

10 cm

Step-by-step explanation:

a^2=b^2+c^2

a^2=6^2+8^2

Answer:

c = 10

Explanation:

Use Pythagoras theorem: a² + b² = c²

where 'a' and 'b' are legs and 'c' is the hypotenuse (the longest side)

Here given: a = 8 cm, b = 6 cm, c = ?

Substituting values:

8² + 6² = c²

c² = 64 + 36

c² = 100

c = √100

c = 10

Solve x^2 + 4x + 8 = 0
Mkey [24]

Answer:

x = -2 + 2 i or x = -2 - 2 i

Step-by-step explanation:

Solve for x:

x^2 + 4 x + 8 = 0

Subtract 8 from both sides:

x^2 + 4 x = -8

Add 4 to both sides:

x^2 + 4 x + 4 = -4

Write the left hand side as a square:

(x + 2)^2 = -4

Take the square root of both sides:

x + 2 = 2 i or x + 2 = -2 i

Subtract 2 from both sides:

x = -2 + 2 i or x + 2 = -2 i

Subtract 2 from both sides:

Answer:  x = -2 + 2 i or x = -2 - 2 i

TV for $500 and the tax is 5.5 what is the original price of the TV
crimeas [40]

Answer:

(since there is no percentage given i will provide two alternate answers one including percentage and one exclusive of percentage)

cost of TV inclusive of tax = $500

we first multiply the tax with total amount

$500 * 5.5

= $500 * 55/10

=$500 * 11/2

= $250 * 11

=$2750

original price of TV = $2750

alternate answer assuming there is a percentage sign with 5.5

the amount of tax on TV is 5.5%

we first multiply the  percentage of tax with total amount

$500 * 5.5/100

=$27.5

original price of TV = $500 - $27.5

= $472.5
