X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
That is the Community Property of Multiplication.
Hope that helps :)
Okay!
1) Round both numbers -
2674 - 2700
1847 - 1800
2) Subtract 2700 and 1800
2700 - 1800 = 900
Therefore, the answer is 900

Answer:
Step-by-step explanation:
- (4a² - 36)/(24 - 8a) =
- 4(
a² - 9) /8(3 - a) =
- (
a² - 9) /2(3 - a) =
- (a + 3)(a - 3)/2(3 - a) =
- - (a + 3) (3 - a)/2(3 - a) =
- - (a + 3) / 2
