Answer:
C) 5.66
Step-by-step explanation:
For a 45-45-90 triangle, the length of each leg length (not including the hypotenuse) is congruent to each other. If 8=y√2, then y=8/√2=4√2=5.66
Step-by-step explanation: In this equation, it's important to understand that the number 5 is the coefficient on the variable M. This just means that -5 "times" M equals -40. So, whenever you see a number next to a variable, it means multiplication.
If we were to solve, we would just divide both sides of the equation by 5. On the left the 5's cancel and on the right, -40 divided by 5 is -8.
Answer:
Part A
x = 4
Part B
10 - 2x = 7 + 5x (x = 4)
6 - 5x = 3 + 2x (x = 4)
7 - 3x = 4 + 6x (x = 6)
6x - 2x² = 3x + 5x² (x = 3x/7) I'm not sure what step is next though
hope this helps.
