Answer:
His mistake is that he didn't multiply it -18 to the negative sign correctly. The negative sign and -18 have to multiply which turns -18 to a positive 18.
Step-by-step explanation:
-15-(-18)=-15 +(-18)
-15+18= -15 -18

Answer:
O The value of x is less than 16.
Step-by-step explanation:
Do the actual work: solve for x:
Divide both sides by 107.06:
16
x < -------------- = 0.149 This does not agree well with any of your answer
107.06 choices. If I had to choose one answer, it'd be the
first one, since "the value of x is less than 16" is
certainly true.
Answer:
-2j - 6
Step-by-step explanation:
3j - 2 + (-5j) - 4
3j - 2 - 5j - 4
<em><u>-2j - 6</u></em>
Answer:
rectangle A:
LENGTH:9
WİDTH:6
rectangle B:
LENGTH:9
WİDTH:3
Step-by-step explanation:
if you want to find the length of a square you should know that in a square all 4 sides lengths are the same so the are is give as 36 to find 1 side of the length we have to divide 36 with 4(because there are 4 sides)
which means the lengths of each side is 9.
it is the same as in rectangle a and b length hasn't changed only the width has changed.
we can also find the width with the information given us about its ratio.
it says that The ratio of area A to area B is 2:1
the length is 9:
we can make it simple like this lets say 2x and 1x has to give us 9
so we can say 3x=9,x=3
to find the width we can say that 2x width is for rectangle A and 1 x is rectangle B. so x was 3:
2x=6
1x=3
these are the widths of rectangle A and B
The length of rectangle is 5 units and width is 4 units.
Step-by-step explanation:
Given,
Area of rectangle = 20
Width of rectangle = w
Length of rectangle = 2w-3
Area = Length * Width
Factorizing
Either;
2w+5=0 =>2w=-5
Or,
w-4 = 0 => w=4
As width cannot be negative, therefore,
width of rectangle = 4 units
length of rectangle = 2w-3 = 2(4)-3 = 8-3 = 5 units
The length of rectangle is 5 units and width is 4 units.
