Answer:
x = 10
Step-by-step explanation:
∵ Both angle ∠A and are corresponding angles.
∠A = ∠B
9x - 40 = 3x + 20
9x = 3x + 20 + 40
9x - 3x = 20 + 40
6x = 60
x = 60/6
x = 10
∴ x = [10]

Step-by-step explanation:
Answer:
Because it is a mixed fraction and it should be renamed in order to solve your problem, for the other one CAN NOT be converted into a mixed fraction.
Step 1. Take out the constants
(4 * 7)xx^2
Step 2. Simplify 4 * 7 to 28
28xx^2
Step 3. Use the Product Rule
28x^1 + 2
Step 4. Simplify 1 + 2 to 3
28x^3
