From the given graph, the image is a trapezoid.
Therefore,
The first option,
"t<span>
he polygon is a rectangle" is incorrect.
The second option "</span><span>Adjacent sides of the polygon are perpendicular." cannot be true as well because trapezoid has one the adjacent sides which is not perpendicular.
Third option" </span><span>Opposite sides of the polygon are parallel", this can't be true as well because only two sides are parallel.
Fourth option " </span><span>The slope of side c is 0.", this is true because line c is a horizontal line with zero rise and maximum run. Therefore,
Slope = 0 </span>÷ 9
<span> = 0
</span>
7/20 * 2/3 = 14/60 = 7/30
Now, 7/30 / 21/4
= 7/30 * 4/21 = 28/630 = 14/315
In short, Your Answer would be 14/315
Hope this helps!
1. Line 3 is the first error. In order to get rid of the 25, you add it to both sides, not subtract. So, your answer is B.
2. Line 1 because it says in the question "4
less than a number" and the equation adds 4, instead of subtracting. Your answer is A.
3. Line 4. To get rid of the 6 in front of 6x, you have to divide by it, but instead they multiply. So, your answer is C.
4. To solve this, you will use the distributive property first:
![4(x-3)=16](https://tex.z-dn.net/?f=4%28x-3%29%3D16)
Turns into:
![4x-12=16](https://tex.z-dn.net/?f=4x-12%3D16)
Get rid of the 12:
![4x=28](https://tex.z-dn.net/?f=4x%3D28)
Divide by 4:
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
Your answer is B.
5. You have to set it up:
![\frac{x}{3} = -11+4](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3%7D%20%3D%20-11%2B4%20)
Just solve for x:
![\frac{x}{3} = -7](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3%7D%20%3D%20-7%20)
Multiply both sides by 3 to isolate x:
![x = -21](https://tex.z-dn.net/?f=x%20%3D%20-21)
Your answer is B.
Hope this helps, if any step doesn't make sense, feel free to tell me!
Answer:
x = 2
Step-by-step explanation:
![4x + 6 = 2x + 10 \\ \\ 4x - 2x = 10 - 6 \\ \\ 2x = 4 \\ \\ x = \frac{4}{2} \\ \\ x = 2](https://tex.z-dn.net/?f=4x%20%2B%206%20%3D%202x%20%2B%2010%20%5C%5C%20%20%5C%5C%204x%20-%202x%20%3D%2010%20-%206%20%5C%5C%20%20%5C%5C%202x%20%3D%204%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B4%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%202)
