Answer:
for the first picture,
5(x-4)+2
= Five multiply the difference between a number x and four more than two.
[tex] - 2( {x + 4)}^{2} - 1[/tex]
= Negative two multiply the number x increased by four to the power of two less than one
second picture,
4 times the quantity x =4x
A number y cubed plus x squared decreased by 7
[tex]7 - ( {y}^{3} + {x}^{2} )[/tex]
5 times the difference of a number x and 4 plus 2=
5(x-4)+2
the difference of x and y is divided by 3 and added by 8 =
[tex]( \frac{x - y}{3} ) + 8[/tex]
