Answer:
x = 5
Step-by-step explanation:
Since the triangles have to be congruent (through SSS), we know that:
2x + 3 = 4x - 7
We simplify this to: 2x = 10
And then: x = 5
The additive identity property states that for every number a, you have

You're showing this property when you write

The sum of two consecutive integers is -23.
Let the larger number = x
smaller number = x - 1
Sum = -23
=> x + x - 1 = -23
=> 2x - 1 = -23
=> 2x = -23 + 1 = -22
=> x = -22/2
=> x = -11
Larger number is -11
180x^2+162x+10

Answer:
First you start with what is in the ( ). 15- 14 is 1. then you do multiplication next. 1* 6. is 6. now you do addition. 6 + 4 = 10
