Answer:
length = 15 feet.
Step-by-step explanation:
This paper is 15 feet across on any side. Who will deliver this monster?
Area = s^2 where s is the length of 1 side.
Area = 225 feet^2 (You sure this isn't inches).
s^2 = area
s^2 = 225 Take the square root of both sides of the equation.
sqrt(s^2) = sqrt(225)
s = 15
Answer:
The second option.
Step-by-step explanation:
Let's see if this will work.
(x+24)(x-24)
Let's open the brackets
x^2 - 24x +24x - 576
= x^2 - 576

The answer is 12>x>-7
Step-by-step explanation:
it's first divided into 2 parts
1 . 15 > 2x - 9
2. 2x - 9 > -23
Then solve them individually.
let's do it,
<u>First half</u>
15 > 2x - 9
15+9 > 2x
24 > 2x
24/2 > x
12>x
<u>Second half</u>
2x-9>-23
2x>-23+9
2x>-14
x>-14/2
x>-7
<u>Joining of the two halves</u>
We have :
12>x>-7
Answer:
x = 13
Step-by-step explanation:
The sum of the exterior angles of a 4 sided polygon is 360
139+ 6x+9x+2x = 360
Combine like terms
139+17x=360
Subtract 139 from each side
17x = 360-139
17x = 221
Divide each side by 17
17x/17 = 221/17
x = 13
