You can use the Pythagorean theorem: a^2+b^2=c^2.

x^2+36=117 so x is 9 or -9 but since this is a length it would have to be positive so the answer is 9.

The Pythagorean Theorem states that the hypotenuse of a right triangle is equal to the square root of the sum of its squared sides, mathematically:

h^2=x^2+y^2, where h=hypotenuse and x and y are the side lengths.

In this case we can say:

(√117)^2=6^2+x^2

117=36+x^2

x^2=117-36

x^2=81

x=√81  since x>0

x=9 cm

Sergio039 [100]

Answer:

241

Step-by-step explanation:

Given the equation to evaluate :

2^8 −10−15÷3

2^8 = 256

256 - 10 - 15 ÷ 3

From BODMAS principle, we evaluate the divison before subtraction :

-15 ÷ 3 = - 5

256 - 10 -5

256 - 15

= 241

What does the remainder theorem conclude given that f(x)x+3 has a remainder of 11?
Slav-nsk [51]

By the remainder theorem of polynomial division, the complete equation is f(-3) = 11

<h3>How to complete the blanks?</h3>

The equation is given as:

f(x)/x + 3

Set the divisor to 0

x + 3 = 0

Solve for x

x = -3

Given that the quotient has a remainder of 11.

It means that:

f(-3) = 11

Hence, the complete equation is f(-3) = 11
