Answer:
Step-by-step explanation:
d^4-81
(d^2)^2-(9)^2
Using formula
(d^2+9)(d^2-9)
Hey! the answer is 6. you have to take the 36 over to the other side which will be 36 obviously and than your left with x to the 2nd and than you will square root 36 to get rid of the squared number and than it’s 6
Answer:
KL = 10
Step-by-step explanation:
JK + KL = JL
2x – 2 + x – 9 = 2x + 8
Combine like terms
3x -11 = 2x+8
Subtract 2x from each side
3x-2x -11 = 2x+8-2x
x-11 = 8
Add 11 to each side
x-11+11 = 8+11
x = 19
KL = x – 9
= 19-9
= 10
Answer:
P = 100
Area = 625
Step-by-step explanation:
Area = s^2
sqrt(area) = sqrt(s^2)
area = 25*25
sqrt(25*25) = sqrt(s^2)
s = 25
P = 4*s
P = 4 * 25
P = 100
Area = s^2
s = 25
Area = 25^2
Area = 625
