Ответ:
3x + 5x = 8
8x = 8
x = 1 is value of x
To find the length of bc substitute 1 for x
ab = 5 ( 1)
ab = 5

Step-by-step explanation:
g+(h+j)+k
correct cause in addition where you put bracket answer will be same
(g+h)+jk
no there jk multiply while other side there is addition so wrong
(g+h)+j+k
as we say in first one it is correct
gh+jk
g(h+j)k
not equivalent due to multiplication
g+h(j+k)
correct and equivalent
