Answer:
x = sqrt(105)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
16^2 + x^2 = 19^2
256 + x^2 = 361
x^2 = 361 -256
x^2 =105
Take the square root of each side
sqrt(x^2) = sqrt(105)
x = sqrt(105)
it would equal the same mixed number. 5 2/3
perimeter means add the side
(x+4) +( x+8)+(2x-3) =P
x+x+2x+4+8-3=P
4x-9 =P
Hey there!
We may ask. What exactly is a term anyways.
Well, a term is a single number, a variable, or a number and a variable that would have to be multiply together. This is what a term would be.
Therefore, as we look above, we see the following equation.
9a+4b-18
18 is a term
4b is a term
9a is a term
This whole thing, would be called an expression, as this is expression something. Perhaps the amount of students who ate ice-cream at a football game, or something similar.
I hope you found this helpful! :)
