Chin made an error in his chart showing the multiplication of the binomial by the trinomial. Which change can be made to correct

stealth61 [152]

Answer:

The expression 6x should be 6x^2.

Step-by-step explanation:

Given is the chart of multiplication of the binomial by the trinomial.

Let's check each element in the chart:-

3x times x^2 = 3x^3

3x times 2x = 6x^2

3x times 4 = 12x

2 times x^2 = 2x^2

2 times 2x = 4x

2 times 4 = 8

From the given chart, we can identify that <u>6x should be 6x^2.</u>

Hence. option B is correct, i.e. The expression 6x should be 6x^2.

Tim and Jane both work for a company that sells boxes of breakfast cereal. the boxes of cereal cost £3.00 and the amount of cere

Alenkasestr [34]

Answer:

25%

Step-by-step explanation:

As the given situation the parameters are below:-

Cost of each box = 3 pounds

Amount of cereal in each box = 160 g

now,

160 g of cereal = 100%

and

25% of 1 box of cereal = 25% of 160 g which is

$= \frac{25}{100} \times 160 g= 40 g$

As per the question, it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided

160 g of cereal costs 3 pounds

and

1 g of cereal will cost

= $\frac{3}{60}\ pounds$

40 g of cereal will cost $40\times \frac{3}{160} = \frac{3}{4}\ pounds$

So, the percentage of $\frac{3}{4}$ the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100

= 25%

Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.
