Ineed understanding which is a, b, or c

see explanation

Step-by-step explanation:

Using Pythagoras' theorem, that is

The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.

Using x instead of ?

(a)

The hypotenuse is the side opposite the right angle, that is 74, thus

24² + x² = 74²

576 + x² = 5476 ( subtract 576 from both sides )

x² = 4900 ( take the square root of both sides )

=

x = 70

----------------------------------------------------------------------

(b)

The hypotenuse x is the unknown side here

x² = 40² + 40² = 1600 + 1600 = 3200

Take the square root of both sides

= ≈ 56.6 ( nearest tenth )

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

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
