Answer:
577,220 will be the population I think
Step-by-step explanation:
370,000/100=3700=1%
3,700*7=25,900
25,900*8=207,200
370,000+207,200=577,220
I think may be 8p +5k . If I’m wrong,... sorry
Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:
![60 + 40 +x = 180](https://tex.z-dn.net/?f=60%20%2B%2040%20%2Bx%20%3D%20180)
Solve for x:
![100 + x = 180\\x = 80](https://tex.z-dn.net/?f=100%20%2B%20x%20%3D%20180%5C%5Cx%20%3D%2080)
So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):
![3x + 60 + 90 = 180](https://tex.z-dn.net/?f=3x%20%2B%2060%20%2B%2090%20%3D%20180)
Solve for x:
![3x + 150 = 180\\3x = 30\\x = 10](https://tex.z-dn.net/?f=3x%20%2B%20150%20%3D%20180%5C%5C3x%20%3D%2030%5C%5Cx%20%3D%2010)
So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
Answer:x=6
Step-by-step explanation:Step-1 : Multiply the coefficient of the first term by the constant 1 • 18 = 18
Step-2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is -9 .
-18 + -1 = -19
-9 + -2 = -11
-6 + -3 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -3
x2 - 6x - 3x - 18
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-6)
Add up the last 2 terms, pulling out common factors :
3 • (x-6)
Step-5 : Add up the four terms of step 4 :
(x-3) • (x-6)
Which is the desired factorization
