Answer:
I think you need to multiply 12 and 7 and then cut that in half
Answer:
11.725%
Step-by-step explanation:
Given that :
True value = 0.904 seconds
Measured time = 1.010 seconds
Experimental error :
(|measured value - True value | / true value) * 100%
(|1.010 - 0.904| ÷ 0.904) * 100%
= 0.106 / 0.904 * 100%
= 0.1172566 * 100%
= 11.725%
Answer:

Step-by-step explanation:
(5,9) and (2,3)
then by distance formula

d²=3²+6²
d²=9+36
d²=45

Answer:
A = x^2 + 4x -21
Step-by-step explanation:
L = x+7
W = x-3
A = L*W
A = (x+7)(x-3)
A = x^2 + 4x - 21
I have no clue you have to do something like x2-x1 over y1-y2 and you get yoyu answer from that.
