14.14 ft

Step-by-step explanation:

In an isosceles triangle, the altitude and median is same. So the height divides the base AB equally such that AD = DB = 10, if the height is CD. So using Pythagoras theorem, we can find the hypotenuse AC in triangle ADC.

h² = b² + a²

AC² = AD² + CD²

AC² = 10² + 10²

AC² = 100 + 100

AC² = 200

AC = √200

AC ≈ 14.14 ft

Hope this answer helps you!!

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

the answer is a.
