Question

Evaluate 2y²(x + y) when x = 1 and y = 5.

Answer 1

300

Explanation:

Evaluate 2 y^2 (y + x) where x = 1 and y = 5:

2 y^2 (y + x) = 2×5^2 (1 + 5)

Hint: | Evaluate 1 + 5.

1 + 5 = 6:

2×5^2×6

Hint: | Evaluate 5^2.

5^2 = 25:

2×25×6

Hint: | Multiply 2 and 25 together.

2×25 = 50:

50×6

Hint: | Multiply 50 and 6 together.

50×6 = 300:
