Answer:
D
Step-by-step explanation:
60°+75°+105°+120°=360°
[Sum of 4 angles of a quadrilateral is 360°]
(x^2+1)(x+2)(x −2)
*ps the ^ means it’s a exponent
Hope I helped <3 sorry if I was wrong :(
it had to be b cuz now all quadrilateral have straight sides
A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers
Measure it hope that helps if not that's on me
