Answer:
The -1 came from factoring.
The equation is multiplied by 8 because 8 could be pulled from 16x-8.
16 can be divided by 8 2 times and 8 can only divided by 8 once.
so factoring it makes the equation 8(2x-1)
Answer: 432 units²
Step-by-step explanation:
The figure is composed by two trapezoids.
The formula for calculate the area of a trapezoid is:
![A=\frac{h}{2}(B+b)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bh%7D%7B2%7D%28B%2Bb%29)
Where "B" is the larger base, "b" is the smaller base and "h" is the height.
Let be
the area of the figure,
the area of the trapezoid on the left and
the area of the trapezoid of the right. Then the area of the figure will be:
![A_f=A_1+A_2](https://tex.z-dn.net/?f=A_f%3DA_1%2BA_2)
![A_f=\frac{h_1}{2}(B_1+b_1)+\frac{h_2}{2}(B_2+b_2)](https://tex.z-dn.net/?f=A_f%3D%5Cfrac%7Bh_1%7D%7B2%7D%28B_1%2Bb_1%29%2B%5Cfrac%7Bh_2%7D%7B2%7D%28B_2%2Bb_2%29)
Substituting values, you get:
![A_f=\frac{16units}{2}(25units+4units)+\frac{10units}{2}(25units+15units)=432units^2](https://tex.z-dn.net/?f=A_f%3D%5Cfrac%7B16units%7D%7B2%7D%2825units%2B4units%29%2B%5Cfrac%7B10units%7D%7B2%7D%2825units%2B15units%29%3D432units%5E2)

Answer:
- 0.5
Step-by-step explanation:
you first change the fractions numbers in to decimal form
so; 2/5 = 0.4
-7/8 = - 0.875
hence; 0.4 + (-0.875)
= - 0.475
in to its simplest form = - 0.5
the answer is - 0.5
Answer:
False
Step-by-step explanation:
Range is defined as the greatest possible number minus the lowest possible number. The highest is 150 (in thousands) and the lowest is 25, meaning the range would be 125,000 and not 150,000.
Hope this helps!
I think its d. Because it is to the nearest thousands. And you cannot find the long sides of the rectangle,because you need another one info. about the number of the long sides or the perimeter or the area. Im happy if i helped you
