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.

A line of 8cm was measured as 8.04cm what is the percentage error​
BlackZzzverrR [31]

Answer:

0.5% error

Step-by-step explanation:

We can use the percentage error formula, which is

\frac{|approx-exact|}{exact}\cdot100.

We know that the approximated value was 8.04, however it is actually 8cm, so we can substitute inside the equation.

\frac{|8.04 - 8|}{8}\cdot100 \\\\\frac{0.04}{8}\cdot100 \\\\0.005\cdot100 \\\\0.5

Hope this helped!

What does the perimeter of this figure consist of?<br><br> semicircle = __<br> line segments = __
Kaylis [27]
Remark
I'm just going to eave a very short note and if you answer quickly in the comments, I'll come back and edit the question.

Argument
If consists of 2 sides and 2 semicircles. Without a width, there is no number to be given. We can get a formula

Fomula
Perimeter = 2*sides + 2pi *w/2 
Perimeter = 2*13 + pi*W
