Which equation shows the Identity Property of Multiplication ? A. a x 1
B. (a + b) + 3 = a + (3 + b)
C. a(b + c) = ab + ac
D. a + a + a = 3 x a

A. a × 1

Step-by-step explanation:

The identity property of multiplication simply states that a number equals itself when multiplied by 1.

a × 1 is the identity property of multiplication.

(a + b) + 3 = a + (3 + b) is associative property.

a(b + c) = ab + ac is expansion.

a + a + a = 3 x a is factoring of like terms.

r and t.

both are 64 degrees.

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
