Step-by-step explanation:
![( {16})^{2} = ( {x})^{2} - ( {8})^{2} \\ 256 = {x}^{2} - 64 \\ 256 + 64 = {x}^{2} \\ \sqrt{320} = \sqrt{ {x}^{2} } \\ 8 \sqrt{5} = x](https://tex.z-dn.net/?f=%28%20%7B16%7D%29%5E%7B2%7D%20%20%3D%20%28%20%7Bx%7D%29%5E%7B2%7D%20%20-%20%28%20%7B8%7D%29%5E%7B2%7D%20%20%5C%5C%20256%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%2064%20%5C%5C%20256%20%2B%2064%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%5C%5C%20%20%20%20%5Csqrt%7B320%7D%20%20%3D%20%20%5Csqrt%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20%20%5C%5C%208%20%5Csqrt%7B5%7D%20%20%3D%20x)
Area of a rectangle = Length * Width
Area = 60cm^2
Length = 4
Width = GH = ? = x
60 = 4*x
solve for x
60/4 = x
x = 15
GH is 15cm
Answer:
x = 20 * s / 300
Step-by-step explanation:
In this case, it is solved by means of a rule of three, that is, we know that 20 of 300 answered yes, but in the case of the strata sample, since it is a value that is not mentioned in the problem, we will assume it as " s "and the people who were selected as" x ". would:
20 x
300 s
Therefore, x:
x = 20 * s / 300
and thus they would give us the number of people that would be selected.
For example, if "s" were 240, it would be:
x = 20 * 240/300
x = 16
that is, 16 people would be selected
Answer:x=61
Step-by-step explanation
856−5x3{131}=2
8(x−9)+5(5−18)+1(15−6x)=2
8x−72−65+15−6x=2
2x=122
x=61
sorry if i'm wrong
Answer:
c = -6
d = 2
Step-by-step explanation:
After reflection about the x-axis:
A --> A'
(x,y) --> (x,-y)
(2,3) --> (2,-3)
(4,3) --> (4,-3)
(2,6) --> (2,-6)
After translation:
(2 + c, -6 + d) --> (-4, -4)
2+c = -4
c = -6
-6+d = -4
d = 2
