Answer:
2+x^2=18 = 2+4^2=18
Step-by-step explanation:
Because when you have the ( ^2) then that means your going to multiply a number by the same number and then 4 times 4 equals 16 and you still have the +2 therefore you add that on the 16 and 16+2 equals 18.
Answer:
Step-by-step explanation:
Simplifying
3.4 + 2(9.7 + -4.8x) = 61.2
3.4 + (9.7 * 2 + -4.8x * 2) = 61.2
3.4 + (19.4 + -9.6x) = 61.2
Combine like terms: 3.4 + 19.4 = 22.8
22.8 + -9.6x = 61.2
Solving
22.8 + -9.6x = 61.2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-22.8' to each side of the equation.
22.8 + -22.8 + -9.6x = 61.2 + -22.8
Combine like terms: 22.8 + -22.8 = 0.0
0.0 + -9.6x = 61.2 + -22.8
-9.6x = 61.2 + -22.8
Combine like terms: 61.2 + -22.8 = 38.4
-9.6x = 38.4
Divide each side by '-9.6'.
x = -4
Simplifying
x = -4
Answer:
A
Step-by-step explanation:
x = 0
y = -3
N> 8
Any value greater than 8 will work for n you choose
And this is why
48 < 6n
same thing as
6n > 48
divide by 6 on both sides
And that leaves you with
n>8
Examples which would work
n=9, n=120, n=756, n = 12
Answer:
a) 
= 8 in
b) When the length of AC = 
in. and BC = 
in. = 10 in
c) When the length of AB = 10.2 in. and BC = 3.7 in. 
= 6.5 in
d) When the length of AB = 
in. and BC = 
in. in. 
= 
in
Step-by-step explanation:
a) When the length of AC = 5 in. and CB = 3 in. we have;
The length of 
= AC + CB (segment addition postulate)
Therefore;
= 5 in. + 3 in. = 8 in.
b) When the length of AC = in. and BC = in. we have;
The length of = AC + CB (segment addition postulate)
Therefore;
= in.+ in. = 10 in.
c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;
The length of = AB - BC (converse of the segment addition postulate)
Therefore;
= 10.2 in.+ 3.7 in. = 6.5 in.
d) When the length of AB = in. and BC = in. in. we have;
The length of = AB - AC (converse of the segment addition postulate)
Therefore;
= in. - in.= in.
