Find the lateral and the total surface area

the answer to that one is b

the result can be shown in both exact and decimal forms.

exact form; 76 · 75, 4911, 4935, 711, 735

decimal form: 5700, 4911, 4935, 711, 735

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
