Triangle ABC is congruent to the Triangle DEF , EF=X^2 -7 , BC = 4X-2 ,Find the value of X? help guys x has two values

x=5

Step-by-step explanation:

Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:

x^2-7=4x-2

x^2-4x-5=0

(x-5)(x+1)=0

x=5,-1

Since a side of a triangle can't be negative, the answer is 5.

no he doesnt because "-16' is negatiive

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
