Answer:
1) A - 42°
2) 74°
3) B - 45°
4) B - 66°
Step-by-step explanation:
1) E = D+H
87 = 45 + H
H = 42°
2) 180 - 50 - D
D = 180 - 44 - 62 = 74°
3) F = 105
H = 180-105 = 75
I + H = C + E
I + 75 = 83 + 37
I = 45°
4) D = 180 - (E + F)
D = 180 - (30 + 57) = 93°
93 = A + 27
A = 66°

Tryna cheat off the I-ready diagnostics huh
Step-by-step explanation:
Let's simplify step-by-step.
−x2+2x−2x2−3x+4+x2
=−x2+2x+−2x2+−3x+4+x2
Combine Like Terms:
=−x2+2x+−2x2+−3x+4+x2
=(−x2+−2x2+x2)+(2x+−3x)+(4)
=−2x2+−x+4
Answer:
=−2x2−x+4
Answer:
Option: d is the correct answer.
The solution set of this system of equations is:
d. {(2, -6)}
Step-by-step explanation:
We are given a system if equations by:
and
i.e.
Also, from equation (2) we get:
Hence, the solution set is: {(2,-6)}
