Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Part 5)
see the attached figure
Step-by-step explanation:
Solve each quadratic equation
Part 1) we have

Adds 32 both sides

Divide by 2 both sides

take square root both sides

therefore
The solutions are (-4,4)
Part 2) we have

Adds 100 both sides

Divide by 4 both sides

take square root both sides

therefore
The solutions are (-5,5)
Part 3) we have

Adds 55 both sides


take square root both sides

therefore
The solutions are (-8,8)
Part 4) we have

Adds 140 both sides

take square root both sides

therefore
The solutions are (-11,11)
Part 5) we have

Adds 18 both sides

Divide by 2 both sides

take square root both sides

therefore
The solutions are (-3,3)
I got area=41.7 m
Step by step:
Find A; 6x4 =24
Find B; you have to subtract 2 from 3.8 to find the length of the dashed line. 1.8x3.5=6.3
Find C; 3.8x3=11.4.
Add together; 11.4+6.3+27=41.7
The area of the given parallelogram is 120.
Step-by-step explanation:
Step 1:
The parameters needed to determine the area of a parallelogram are the base length and height.
The base length of this parallelogram is 15 inches while its height is 8 inches.
The area of a rectangle is determined by multiplying the base length with the height.
Step 2:
The area of the parallelogram 
Here the base length is 15 inches and the height is 8 inches.
The area of the parallelogram 
So the area of the given parallelogram is 120.
Answer:
55 cookies in 80 mins
Step-by-step explanation:
1 hour has 60 mins
so 25/60=0.417
0.417/3=0.139
0.139x4=0.556
so he can eat 55 cookies in 80 mins
