How to solve-
PEMDAS shows that you will start off by multiplying. A negative times a positive equals a negative and a negative times a negative equals a positive.
-1 • 5= -5
and
-1 • -7 = 7
-5+7= 2
Answer:
400
Step-by-step explanation:
Divide 500 by 5 and multiply the quotitent by 4
7428. 25+15/4*18+25*12+16*3.
Simple,
writing an equation to find the sides,
x+2+x+2+x+x=44
4x+4=44
Subtract 4 from both sides, making the equation look like this,
4x=40
Divide by 4
x=10.
To check it, just plug it back into original equation.
10+2+10+2+10+10=44
It works. :)
