The answer is C = {-7, 1, 9, 17}
A).(x - 10) X (x - 4)
(4 - 10) X (4 - 4)
6 X 0 = 0

a^2 + b^2 = c^2
Let the length of the ladder be x.
One side is x - 16.
The other side is x - 8.
</span><span>(x-16)^2 + (x-8)^2 = x^2
</span>
x^2 - 32x + 256 + <span>x^2- 16 x+64 = x^2
x^2 - 48 x + 320 = 0
( x- 40 ) (x-8) = 0
x = 40 or x= 8
we discard the second so x = 40

You are looking for a number that, when multiplied by the same number, equals 30. This is can be written as x times x, or
= 30. To find the answer, all you have to do is take the square root of 30.
is approximately 5.477
Answer: 51.5 inches
Step-by-step explanation: The high jumper will be making seven jumps, increasing by 1/2 inch each time. In order to calculate how much it will be moved up from the original position we need to multiply 1/2 x 7 jumps = 3.5 inches. In order to calculate how high the bar will now be, we need to add together the original 48 inch height plus the 3.5 inches that it was been raised, so they total is 51.5 inches high.
