Pythagorean theorem
marta [7]

Answer:

x = 8

Step-by-step explanation:

a^{2} +b^{2} =c^{2} \\ so 8^{2} +b^{2} =\sqrt{80} ^{2}

rearrange the formula:

\sqrt{80} ^{2} - 8^{2} = b^{2}

80 - 64 = b^2

b^2 = 16\\b  = \sqrt{16}

\sqrt{16}  = 4

x = 4+4 = 8

Simplify the following expression 6X2 plus 8X -3 minus 3X2-6
Murrr4er [49]

Answer:

-24

Step-by-step explanation:

I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,

so 6*2=12,8*-3=-24,-3*2=-6

12+-24-6-6,

12-24=-12,-6+-6=-12

-12+-12=-24

-how to solve-
First, do 2 to the second power and get 4.
Next, do 12-2+4 divided by 8.
Next do multiplication: there’s no more.
Next do division: you can’t do 4 divided by 8 so instead, do 12-2 = 10 plus 8.
Hope this helps!
