The answer is C.

Remember FOIL: First terms, outside terms, inside terms, last terms.

The first terms in each of the parentheses are 3x and 4x^2. Multiply them together. 3x × 4x^2 is the first part.

The outside terms in each of the parentheses are 3x and 5. Multiply them together. 3x * 5 is the second part, which eliminates A, as that has no 3x * 5.

The inside terms in each of the parentheses are -1 and 4x^2. Multiply them together to get -1 * 4x^2. This eliminates B as it states that the third multiplication is 1 * 4x^2.

Therefore, the correct expansion is Option C.

A chocolate bar measures 30 mm wide, 70 mm long, and (or 4.5) mm high. Will's Wrapping Company is making a wrapper to cover the

Hey there! I'm happy to help!

First, let's find the area of the top of the bar.

30×70=2100

This is the same as the bottom of the bar, so we have another 2100 mm, giving us 4200 in total.

Now we want to find the two long sides. This is 70×4.5, which is 315. Since there are two of these sides, we have another 315, giving us 630 in total there.

Now we have the short sides.

30×4.5=135

135×2=270

Now, we add up all of these measurements.

4200+630+270=5100

Therefore, Will's Wrapping Company will need 5100 mm² of paper to make their wrapper.

Have a wonderful day! :D
