Which expressions are equivalent to g+h+(j+k)? Check all that apply.

g+(h+j)+k

(g+h)+jk

(g+h)+j+k

g+(hj)+k

gh+jk

g(h+j)k

g+h(j+k)

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

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
