Square has all perimeter lines identical. to find the length of a side you can use a^2 = b^2 + c^2
24^2 = 576

as b and c are equal you can just divide 576 by 2 to get 288.
square root of 288 = 16.97 feet

Square has legnth and width equal

if we draw a line from one cornder to the other, we get the diagonal
we also get 2 right triangles with diagonal=hyposonuse

and the sides of the room are the legs
since squae has all sides equal
legs are equall

a^2+b^2=c^2
a and b are legs
c=hyposonuse
a=b
a^2+a^2=c^2
c=24
2a^2=24^2
2a^2=576
divide 2
a^2=288
sqrt both sides
a=12√2

periimiter=4a
P=4*12√2
P=48√2 ft

Write an equation for the translation of x^2 + y^2 = 49 by 7 units right and 4 units up
Tatiana [17]

Answer:

(x - 7)² + (y - 4)² = 49

Step-by-step explanation:

Given

Equation: x² + y² = 49

Required:

New Equation when translated 7 units right and 4 units up

Taking it one step at a time.

When the equation is translated 7 units right, this implies a negative unit along the x axis.

The equation becomes

(x - 7)² + y² = 49

When the equation is translated 4 units up, this implies a negative unit along the y axis.

(x - 7)² + (y - 4)² = 49

The expression can be further simplified but it's best left in the form of

(x - 7)² + (y - 4)² = 49

|-3 + 15| what is the sum (answer) ? I think it is 12 but my friend thinks it is 18. Who is right?
Aliun [14]
I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.
