3 if 5 times a number plus two is 17, then we can say 5x+2=17 if we subtract two on each side we have 5x=15, divide each side by 5 and you get x=3 so your answer is 3
5 is 4000 crickets ((((250) times 2) times 2) times 2) times two)
Answer:
![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
Step-by-step explanation:
Hello!
A trinomial is a expression consisting of three different terms
To turn this into a trinomial we multiply everything to each other
<u> 3x </u>
3x * x = ![3x^{2}](https://tex.z-dn.net/?f=3x%5E%7B2%7D)
3x * 10 = 30x
<u> 8 </u>
8 * x = 8x
8 * 10 = 80
Now we put them all together in an equation
![3x^{2} +30x+8x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B30x%2B8x%2B80)
Combine like terms
![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
The answer is ![3x^{2} +38x+80](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B38x%2B80)
Hope this helps!
The answer to c. Is 8t+12g
Answer:
Given:
and
.
Prove: ![r\parallel t](https://tex.z-dn.net/?f=r%5Cparallel%20t)
Since
, By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly
, it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
,
,
and ![\angle 4\cong \angle 8](https://tex.z-dn.net/?f=%5Cangle%204%5Ccong%20%5Cangle%208)
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that
.
