The perimeter of a square is 44. Find the length of a diagonal.

It will be sqrt(242) or approximately 15.556

Step-by-step explanation:

Knowing that the perimeter is 44, you will divide it by 4 to get the length of the sides. It's best to think of this as a Pythagorean Theorem problem.

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

Substitute 11 into variable "a" and "b" and square them... resulting in

121 + 121 = c^2

242 = c^2

SO

sqrt (242) = c

PS. sqrt means square root of

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
