Step-by-step explanation:
fe+3f+2f+2=2f-2+5
fe+5f+2=2f+3
fe+2=-3f+3
e=2/-3+3f

the ratio of the cost, is tandem to the ratio of the areas, because, to get the cost for the mulch, you have to first know how many square meters/feet have, and then you apply the cost evenly, now, the cost is just a factor, therefore, the ratio is retained.
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
Part A.
1. If the parent function 
is shrinked (looks more flattened out and fatter) with coefficient 0<k<1, then its equation is 
2. If the function 
is fatter translated 11 units to the left, then its equation becomes
3. If the function 
is translated 5 units down, then its equation becomes
where 0<k<1.
Answer 1: correct choice is B.
Part B.
1. If the parent function is shrinked (looks more flattened out and fatter) with coefficient 0<k<1, then its equation is
2. If the function is fatter translated 8 units to the right, then its equation becomes
3. If the function 
is translated 1 unit down, then its equation becomes
where 0<k<1.
Answer 2: correct choice is A.
