Explanation

Given expression: 68 - 13 + 21 ÷ 3 × 2

Following order of operations:

1. Division: 21 ÷ 3 = 7

2. Multiplication: 7 × 2 = 14

3. Now, the expression becomes:

68 - 13 + 14

= 68 - 13 = 55

= 55 + 14 = 69

Explanation

To determine significant figures in 10.03:

• All non-zero digits are significant → 1 and 3
• Zeros between non-zero digits are significant → 0 between 1 and 3
• Zeros after a decimal and a non-zero digit are also significant → the 0 after the decimal is significant

So: 1, 0, 0, 3 → 4 significant figures

Explanation

To find the remainder, we can use the Remainder Theorem, which states that the remainder of a polynomial f(x) divided by x - a is f(a). In this case, we need to divide by x + 2, so we'll use x = -2.

f(x) = 2x⁴ - 3x² + 5x - 7

f(-2) = 2(-2)⁴ - 3(-2)² + 5(-2) - 7

= 2(16) - 3(4) - 10 - 7

= 32 - 12 - 10 - 7

= 32 - 29

= 3
