Answer:
x=18
each triangle will equal 180. 38+56=94. 180-84= 86. then 86+38=124 +38 for the other corner because they have to be equal, 124+38=162 180-162= 18
Answer: The first one : -2x^2 + 20x - 54
Step-by-step explanation:
y = -2(x-5)^2 - 4
= -2(x^2 - 10x + 25) - 4
= -2x^2 + 20x - 50 - 4
= -2x^2 + 20x - 54
Step-by-step explanation:
2x+4 +3x = 2x +2 +1
4+x= 2x+3
4-3=2x-x
1=x
x=1
Answer:
