Answer:
The area of the rectangle in polynomial form is 
Step-by-step explanation:
Given
Shape: Rectangle


Required
Area of the rectangle
The area of a rectangle is calculated as thus;

By substituting
for height and
for width; This gives

Expand the bracket

Open each bracket



Hence, the area of the rectangle in polynomial form is 
Step-by-step explanation:
Principal(P) =$2200
Rate(R) =4%
Time(T)=2 yrs
Simple Interest=PTR/100
I=2200*4*2/100
=$176
Answer:
B) 40 ft
Step-by-step explanation:
Use the picture for a reference.
1. We can see the diagonal forms a triangle. Since the angles of a rectangle are right, we can use the Pythagorean Theorem to solve for x.
2. The Pythagorean Theorem
a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
a = 30 ft (width)
b = x ft (unknown length)
c = 50 ft (diagonal)
3. Substitute in the values:
30^2 + x^2 = 50^2
900 + x^2 = 2500
x^2 = 1600
x = 40
The length of the field is 40 ft.
Each must have 3
3 times number of studnets=popsicles she must buy
3 times 25=75
she needs 75 posicles
number of poples bought=number per box times number of boxes
needs 75
75=15 times number of box
divide both sides by 15
5=number of boxes
should buy 5 boxes
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
Slope = (4-7)/(7-1)
Slope = -3/6
Slope = -1/2
