Answer:
7a^4 +35a^2 +28a
Step-by-step explanation:
Area is the product of height and width:
area = height × width
= 7 × (a^4 +5a^2 +4a)
area = 7a^4 +35a^2 +28a . . . . . . use the distributive property
Answer:
Graph A
Step-by-step explanation:
Graph A has a better fit line because the data fits more closely to it without as much spread. In Graph B, the line fits 2 points and falls in the middle but has a much wider spread of data.
5=−(−z+3)
Simplify:
5=−(−z+3)
5=z+−3(Distribute)
5=z−3
Flip the equation.
z−3=5
Add 3 to both sides.
z−3+3=5+3
z=8
