Solve by grouping if you are able to find distinct factors that multiply to the last term and add to the middle term...this method is rather easy with easy to manage numbers. Complete the square if you cannot find distinct factors that multiply to the last term and add to the middle term. Completing the square helps when the equation is in the form of a parabola.
Answer:
The value of x is 10, and the value of y is 6
Step-by-step explanation:
ABC and GEF are congruent
so
x - 8 = 2
x = 10
x - y = 4
10 - y = 4
y = 10 - 4
y = 6
Answer
x = 10, y = 6
Answer:
The number of faces is 29
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
![V- E + F = 2](https://tex.z-dn.net/?f=V-%20E%20%2B%20F%20%3D%202)
In this problem we have
![V=16](https://tex.z-dn.net/?f=V%3D16)
![E=43](https://tex.z-dn.net/?f=E%3D43)
Substitute in the formula and solve for F
![16- 43 + F = 2](https://tex.z-dn.net/?f=16-%2043%20%2B%20F%20%3D%202)
![-27 + F = 2](https://tex.z-dn.net/?f=-27%20%2B%20F%20%3D%202)
![F = 2+27](https://tex.z-dn.net/?f=%20F%20%3D%202%2B27)
![F = 29](https://tex.z-dn.net/?f=%20F%20%3D%2029)
Answer:
David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month
Step-by-step explanation:
I'm not clear on your actual question, but I'm guessing you want to know how much money he has saved each of the last four months.
2150 - 1350 = $800 saved over the past four months
$800 / 4 months = $200 saved per month
