Answer:
1. <ABC≅ <DEF - given
2. <GHI≅<DEF- given
3. <DEF≅<GHI- Symmetric property
4. <ABC≅<GHI- transitive property
5. m<ABC=m<GHI- definition of ≅ angles
Step-by-step explanation:
5(x²+x-2x-2)
5(x²-x-2)
5x²-5x-10
you can also simplify to x²-x-2.

Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
