Using pythagoras a^2 + b^2 = c^2
8^2 + 3^2 = c^2
64 + 9 = 73
The square root of 73 is 8.54
So the length of the diagonals are 8.54cm
Hi.
The answer to your question is:
C. <em />y = 450 + 225<em>m</em>
-4x - 6 = 10
To solve the equation, you will have to isolate the x. Because of the equal sign, what you do to one side, you do to the other.
-4x - 6 = 10
Do the opposite of PEMDAS. First add 6 to both sides
-4x - 6 (+6) = 10 (+6)
-4x = 10 + 6
-4x = 16
Isolate the x, divide - 4 from both sides
-4x/-4 = 16/-4
x = 16/-4
x = -4
-4 is your answer
hope this helps
