Answer:
z=55
Step-by-step explanation:
The two angles form a straight line which is 180 degrees
80 + 2z-10 = 180
Combine line terms
70 +2z = 180
Subtract 70 from each side
70-70 +2z= 180 -70
2z = 110
Divide by 2
2z/2 = 110/2
z = 55
Answer: 1) Let's simplify step-by-step.
x22(x+y)−y2
Distribute:
=(x22)(x)+(x22)(y)+−y2
=x23+x22y+−y2
Answer:
=x23+x22y−y2
2)Let's simplify step-by-step.
x4+x2y2+y4
There are no like terms.
Answer:
=x4+x2y2+y4
so a quadrilateral is a figure with 4 sides. So looking at the picture I see 5 rhombi and 7 squares. So all together thats 12 quadrilaterals
So to find the ration you have to do:
amount of thing: whole
so in this case it would be
12:24
which you can simplify
normally you'd simplify to 1:2 but that doesn't seem like an option so I'd go with the one closest to that ratio
Answer:
your answer would be -13.8y
