You would use order or operations to solve this problem

4 to the second power is 16 -------> 12+16= 28

Your answer would be 28

A square has a diagonal that is 26 feet long. What is the perimeter of this square?

Bond [772]

answer:

52 $\sqrt{2}$

step-by-step explanation:

we can use the 45-45-90 triangle theorem for this: x, x, x $\sqrt{2}$

this is because this is a square

squares have two sides of the same length, and the diagonal is different
the x's stand for the sides, whereas the x $\sqrt{2}$ stands for the diagonal

x $\sqrt{2}$ = 26

x = 13 $\sqrt{2}$

now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4

13 $\sqrt{2}$ X 4 = 52 $\sqrt{2}$

A certain circle can be represented by the following equation x^2+y^2+18x+14y+105=0 What is the center and radius of the circle?

Dimas [21]

Answer:

Center of the circle is (-9, -7)

Radius of the circle = 5 units

Step-by-step explanation:

Given question is incomplete: here is the complete question.

Certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0.

What is the center of this circle ?

What is the radius of this circle ?

Since equation of the circle has been given by the equation,

x² + y² + 18x + 14y + 105 = 0

Now we will convert this equation to the standard form of the circle.

x² + 18x + y² + 14y = -105

[x² + 2(9)x] + [y² + 2(7)x] = -105

[x² + 2(9)x + 9²] + [y² + 2(7)y + 7²] = 9² + 7² - 105

(x + 9)² + (y + 7)² = 81 + 49 - 105

(x + 9)² + (y + 7)² = 25

(x + 9)² + (y + 7)² = 5²

By comparing this equation with the standard equation of the circle → (x - h)² + (y - k)² = r²
