In -2^2 since the negative sign is not in parentheses you would solve it as 2×2=4 and then have the negative sign so it would be -4. With the parentheses you are saying that the term you are squaring is (-2) and two negatives make a positive so it would be (-2)×(-2)= 4.

Raoul has to finish a 473-page book in a week. He decides to read the same number of pages each weekday and 30 extra pages on Sa

hodyreva [135]

Answer:

$59$ pages

Step-by-step explanation:

Variable:

x = number of pages he has to read on a weekday

x + 30 = The number of pages read on Saturday and Sunday

$5x+2(x+30) = 473$

$==> 5x + 2x + 60 = 473$

$==> 7x =413$

$==> x = 59$

Meaning that Raoul has to read 59 pages on Wednesday
