First distribute the negative
(-x+2)(x-7)
Next multiply -x by x
Then multiply 2 by x
Then multiply -x by -7
Then multiply 2 by -7
-x^2+2x+7x-14
-x^2+9x-14 is your answer
Solution for what is 147.1% of 155
155/x=100/147.1
(155/x)*x=(100/147.1)*x - we multiply both sides of the equation by x
155=0.67980965329708*x - we divide both sides of the equation by (0.67980965329708) to get x
155/0.67980965329708=x
228.005=x
x=228.005
now we have:
147.1% of 155=228.005
