To find the final term to compete the square you need to divide the 'x' term by 2 then square it

- equivalent equation
For question 4 the answer is yes and for question 5 the answer is false
P = 12 + 6 + 8,5 = 18 + 8,5 = 26,5 mm
A = 12 × 4 / 2 = 48 / 2 = 24 mm²
Answer:
The slope is 2
Explanation:
The equation is written in y=mx+b
M would always be the slope and b the y intercept
Hope this helps!!
