Answer:
− 5 x − 16
Step-by-step explanation:
-2*x and -2*4= -2x+-8
-2x+3x= -5x
-8-8= -16
-5x-16
-4(3m-3)+(-10+8m)
12m+12-1+8m
12m+8m = 20m
+12 -1= +11
answer: 20m+11
*note negative times a negative equals positive and negative times positive is negative
first: you multiply -4 by 3m which is -12m.
second: you multiply -4 by -3 which is +12
third: find the invisible which is 1. (located right here: +(1) (-10+8m)
fourth: multiply invisible 1 by -10 which is -10
fifth: multiply invisible one by +8m which is +8m
sixth: combine like terms
seventh: answer
Answer:
12 square cm correct to 2 significant figures
Step-by-step explanation:
Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm
To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.
The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.
11.76 square cm = 12 square cm correct to 2 significant figures
Answer:
$100.00
Step-by-step explanation:
If we are rounding to the nearest 10, then we only have to look at 96. Since 6 is bigger than 5, we round up to 100.
Since both y’s are negative you can combine them to make -6y=1 then you divide -6 on each Side to get y=6
