We have to calculate the radius
Radius: Distance between the points (8,2) and (3,7)

Given two points (x₁,y₁) and (x₂,y₂) the distance between these points will be:
Distance=√((x₂-x₁)²+(y₂-y₁)²)

In this case:
Distance=radius=√((3-8)²+(7-2)²)=√(25+25)=√50

Area of a circle=πr²
Data:
r=√50

Therefore:
Area of this circle=π((√50)  u)²=50π u²≈157.1 u².

Answer: the area would be:    50π u²      or        157.08 u²

Gables property Corp is leasing office buildings with an area of 49x^2 + 70x +25
Hoochie [10]

Answer:

Given: Gables property Corp is leasing office buildings with an area of 49x^2 + 70x+25

⇒ Area = 49x^2 + 70x+25

we can write this as:

Area = (7x)^2+2\cdot (7x) \cdot (5) + (5)^2            .....[1]

Use the  identity formula:

(a+b)^2 = a^2+2ab +b^2

then, by using this formula in [1] we have;

Area = (7x+5)^2

or

Area = (7x+5)(7x+5) square units

Area of building = l \times w where l is the length and w is the width respectively;

⇒ l = w = 7x+5 units

Therefore, the possible length and width of the building is;

l = 7x+5 units

w = 7x+5 units

As we know that the Area of a square is equal to side times side . Since each side of a square is the same, it can simply be the length of one side squared.

Therefore, the possible shape of the building is Square.

An energy bar company manufactures peanut butter and chocolate bars.
Ivenika [448]

Answer:

sold 120 chocolate bars

sold 140 peanut butter bars

Step-by-step explanation:

x = peanut butter bars

y = chocolate bars

x + y = 260, total lbs

0.25x + 0.30y = 71, money

solve double variable equation

multiply -4 on both sides for 2nd equation

-x + -1.2y = -284

add both equations together

-0.2y = -24

y = 120

x = 260 - 120

x = 140

sold 120 chocolate bars

sold 140 peanut butter bars
