Answer:
The term 6x should actually be 6x²
Step-by-step-explanation:
The illustration referenced, which depicts the multiplication of the trinomial with the binomial, is provided in the image below.
To identify where Chin's multiplication went wrong and to establish the correct expression, we'll analyze each multiplication performed. Therefore, we have:
3x*x² = 3x³
3x*2x = 6x² (the mistake occurred here, as Chin recorded it as 6x in the chart)
3x*4 = 12x
2*x²=2x²
2*2x = 4x
2*4 = 8
Thus, the term 6x should indeed be corrected to 6x²
The y-coordinate of P' is -10.
Step-by-step explanation:
It is given that triangle PQR has vertices at P(–2, 6), Q(–8, 4), and R(1, –2).
The translation rule is
To determine the image of point P, referred to as P', we must substitute the coordinates of P(-2,6) to arrive at;
Thus, the y-coordinate of P' is -10.
The sales increased by 44.4%.
Step-by-step explanation:
- Let's calculate this cumulatively
- 90 of 10% = 9, resulting in 99
- 90 of 10% = 9, leading to 108
- 90 of 10% = 9, which becomes 117
- 90 of 10% = 9, amounting to 126
- 90 of 4% = 3.6, giving 129.6
- 90 of 0.044% = 0.0396, approaching 129.99
- This indicates an approximate 44.44 increase, affirming that there was indeed growth.
- Always begin with the first approximation rule by using 50% of 90 if the result is above 130.
- Then lower it to 40% of 90 to check if sales drop below 130.
- The approach should always commence with 50, 40, 30... 10 percentages.
- As an alternative, use 10, 1 or decimal values.
- Establish approximations using decimals and rounding up simplifies the computation.
I identified the missing equations. They include:
w(w – 2) = 48
w(w + 2) = 48
2w(w – 2) = 48
<span>2w(w + 2) = 48
</span>
The shape of the mosaic will be rectangular, as indicated by the use of width and length terminology.
For a rectangle, area = length * width
As the length exceeds the width by 2, we have length = w + 2.
For the rectangle area, we get = (w + 2) * w.
<span>The appropriate equation to use is: w(w + 2) = 48</span>
