Answer:

90ft^2

Step-by-step explanation:

First find the area for the small rectangle on the side

The demensions are 6 by 3

multiply to get the are which is 18

now find the area of the triangle

Area of triangle = L*W/2

so you you find the bottom sides length which is 15-3 which is 12. (you minus 3 because thats part of the rectangle)

then you figure out the length which you can see the top half is 6 and then the then the other half of that line is 6 add them together and you get 12 as the length

now multiply the length and width 12*12= 144

now divide 144 by 2 and you get 72

add the area of the rectangle with the area of the triangle and you get 90ft^2

Two consecutive even numbers are such that five times the smaller number , subtracted from eight times the bigger gives 58. Find

olga55 [171]

Answer:

$14\text{ and }16$

Step-by-step explanation:

Let the smaller number be $x$ . Since they are consecutive even numbers, the larger number can be represented by $x+2$ .

Therefore, we have the following equation:

$8(x+2)-5x=58,\\8x+16-5x=58,\\3x=42,\\x=\boxed{14}$

Thus, the larger number is $x+2=\boxed{16}$

in parallelogram ABCD, AB=(6x-2) feet DC=(3x+13) feet and AD=5 feet. Find the number of feet in the perimeter of the parallelogr

sweet [91]

Answer:

66 feet

Step-by-step explanation:

Parallelograms have 2 pair of parallel sides that are congruent to each other.

In parallelogram ABCD, we can say:

AB = DC

and

BC = AD

AB and DC are given, and they are equal. So we can say:

AB = DC

6x - 2 = 3x + 13

Now we can solve for x:

6x - 2 = 3x + 13

6x - 3x = 13 + 2

3x = 15

x = 15/3

x = 5

So,

AB = 6x - 2

AB = 6(5) - 2 = 28

So, DC = 28

We are also given AD = 5, so BC = 5 as well [since AD = BC]

Now, we know the length of all 4 sides.

The perimeter is the sum of all 4 sides. Hence,

Perimeter = 28 + 28 + 5 + 5 = 66 feet

The equation of a circle is (x-2) squared + (y-6) squared =64. What is the center and radius of the circle.

evablogger [386]

Answer:

The center (2,6) and the radius is 8

Step-by-step explanation:

The equation of a circle is (x-h)^2 + (y-k)^2 =r^2

where (h,k) is the center of the circle and r is the radius

We have

(x-2)^2 + (y-6)^2 =64

(x-2)^2 + (y-6)^2 =8^2

The center (2,6) and the radius is 8
