If r= - square root2 and a^5= 32square root2, what is the first term of the sequence?

8√2

Step-by-step explanation:

r=-√2

a5=32√2

an=a1(r)^{n-1}

32√2=a1(-√2)^{5-1}=a1×(-√2)^4=a1×4

step-by-step explanation:

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
