Which of the following is the area of a quadrilateral with vertices at (-4,2),(1,2),(1,-3) and (-4,-3)
kow [346]

Answer:

The correct option is B.

Step-by-step explanation:

The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).

Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Use distance formula to find the side length.

AB=\sqrt{(1-(-4))^2+(2-2)^2}=\sqrt{5^2}=5

BC=\sqrt{(1-1)^2+(-3-2)^2}=\sqrt{(25}=5

Since both consecutive sides are equal therefore it is a square.

Area of a square is

A=a^2

Where, a is side length.

The side length of the square is 5. So, area of ABCD is

A=(5)^2

A=25

Therefore the area of quadrilateral is 25 units square. Option B is correct.

Jimmys garden has a length of 2b
GrogVix [38]

Answer: 18b + 2

Step-by-step explanation:

Length: 2b + 4

Width: 7b + 2

I assumed the garden is a rectangle shape since the length and width are different.

Perimeter = 2( L + w)

Then we just plug the values in.

2 (2b + 4 + 7b + 2)

2 (9b + 6) = 18b + 12

So, the equation for the perimeter of Jimmy's garden will be 18b + 2.

Dmitry [639]

Answer:

X=10, x=4

Step-by-step explanation:

first, divide 14 by 2, and square it; giving you

x^2-14x+(7)^2=-40

Because 7^2 is 49, you have to add 49 to the other side; giving you

x^2-14x+(7)^2=9

Then factor the left side; giving you (x-7)^2=9

Take the square root of both sides, giving you

(x-7)^2= plus or minus 3

Then solve to get two solutions, 10 and 4
