Step-by-step explanation:
A1= area of the rectangle
A1= 4yd • 10yd
A1= 40 square yd
A2= area of the part of the circular section
A2= 180°• pi • 4 square yd/360°
A2= 180° • 16yd • pi/ 360°
A2= 16yd•pi/2
A2= 8yd•pi
A2= 25,12yd
A= areo of rhe shaded portion
A= A1-A2
A= 40yd-25,12yd
A= 14,88yd

Step-by-step explanation:
there are already 44 dogwood trees
there will be 70 dogwood trees by the end of the day
we take how many dogwood trees there already are and subtract them from what there will be
70-44=26

Answer:
3rd box: -1 +14a +7h
Step-by-step explanation:
You will need to "simplify" the difference, then do the division by h.
f(a +h) = (6 -(a +h) +7(a +h)^2) = 6 -a -h +7(a^2 +2ah +h^2)
f(a +h) = 6 -a +7a^2 -h +14ah +7h^2
Then the difference is ...
f(a +h) -f(a) = 6 -a +7a^2 -h +14ah +7h^2 -(6 -a -7a^2)
f(a +h) -f(a) = -h +14ah +7h^2
Dividing this by h, we get ...
(f(a +h) -f(a))/h = (-h +14ah +7h^2)/h = -1 +14a +7h
