Answer:
should be 80, angle 50 is congruent on both sides to 50+50 equals 100. The triangle sum theorem says a triangle adds up to 180 degrees so we are left with 80, X=80 degrees
1. Each term in this polynomial has a common factor of 
:
2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.
3. You can use the same approach as in (2), or recall that 
:
4. Recall that a difference of squares can be factored as 
. So
Answer:
Because there are fewer than 30 (not no more than 30) one of the answer i x+y < 30
Because he needs both small and large another answer is x>0 and not x 0
Finally because he need at least dozen large cones the last answer is y
Step-by-step explanation:
Answer:
9 - √6
Step-by-step explanation:
(3 + √3)(3 - √2) ➡ 9 - 3√3 + 3√3 - √6
9 - √6
Is there a picture of the data set? I cannot give you an exact answer without the actual data values, but I can explain how to solve it.
The mean absolute deviation basically tells the average of how much each data value deviates from the mean of the entire data set. Therefore you just find the difference between each value in the data set and 57. Then you take all the differences and find the average by adding them all up and dividing by the number of values.
