Answer:
= -5√7 -(√2)
Step-by-step explanation:
3√7- √7 -2√7+√8 -5√7-3√2
=3√7- √7 -2√7 -5√7+√8 -3√2 (first we place similar radicands together)
=-5√7+√8 -3√2 ( solve the similar radicands)
=-5√7+√2³ -3 (2^1/2) ( break 8 into powers of 2)
=-5√7+ (2)^3/2 -3 (2^1/2) (solve 2 power with the radical sign)
= -5√7+(2^1/2){ 2-3} ( taking2^1/2 as common)
= -5√7+(2^1/2){ -1} ( solving the co - efficients of 2^1/2)
= -5√7 -1 (2^1/2)
= -5√7 -(√2) {answer}
Answer:
(x+4)^2 + (y-6)^2 = 29
Step-by-step explanation:
The center-radius form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k)
Replacing the center C(-4,6):
(x+4)^2 + (y-6)^2 = r^2
then replacing the point (-3,1):
(-3+4)^2 + (1-6)^2 = r^2
1 + 25 = r^2
then the equation of the circle is:
(x+4)^2 + (y-6)^2 = 29
Answer:
6
Step-by-step explanation:
if you take the number of paws minus the number of noses you get your answer so if you take
24 - 6 ( noses) =18
(4paws x6 lions= 24)
so the number of lions is 6
Answer: all of the sides are 10ft long

Answer:
n = 9/4 = 2.250
Step-by-step explanation:
Rearrange: 4*n-(9)=0
Solve: 4n-9 = 0
4n = 9
n = 9/4 = 2.250
answer: n = 9/4 = 2.250
