Answer:
(7 x - 1) (x + 1)
Step-by-step explanation:
Factor the following:
7 x^2 + 6 x - 1
Factor the quadratic 7 x^2 + 6 x - 1. The coefficient of x^2 is 7 and the constant term is -1. The product of 7 and -1 is -7. The factors of -7 which sum to 6 are -1 and 7. So 7 x^2 + 6 x - 1 = 7 x^2 + 7 x - x - 1 = (7 x - 1) + x (7 x - 1):
(7 x - 1) + x (7 x - 1)
Factor 7 x - 1 from (7 x - 1) + x (7 x - 1):
Answer: (7 x - 1) (x + 1)
So first you need to find the area of the building site which is:
length x width
39.5m x 32.5m
= 1283.75
We know that one square meter costs 185.50 euros.
1
= 185.50 euros
1283.75
= <u>238135.625 euros</u>
I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are <u>238134.86 and 238135.86.</u>
sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!
