Answer:
Step-by-step explanation:
3/7x+5=8
Subtract 5 from each side of the equation.
3/7x=3
Divide each side by 3/7
X=3/ (3/7)
To divide by a fraction, we Can flip the fraction, (7/3) and multiply.
X= 3(7/3)
X=21/3
X=7

Answer: find the answer in the explanation.
Step-by-step explanation:
To use the Pythagorean theorem to prove if a triangle with the side lengths 7,14,28 is a right triangle, you will square 7 and add it to the square of 14. The square root of the sum will be equal to 28 if it is a right angle triangle. Otherwise, it is not.
(7^2 + 14^2) = 49 + 196
245
Find the square root of 245
Square root = 15.65
Since it is not 24, the triangle is not a right angle triangle.
