Answer:
absolute value is the well absolute value of a number and to do this you need to find a number for example -5 and take away the negative sign so it would be 5 so the absolute value of -5 is 5
Step-by-step explanation:
9x+5
Step-by-step explanation:
Answer:number of children negative for chicken pox=28
Step-by-step explanation:
Number of children positive for chicken pox =18 out of 30
Therefore number of children negative for chicken pox is 12 out of 30 ie ( 30-18)
Such that the ratio of positive tested chicken pox children to negative tested chicken pox children =18:12
Therefore total ratio =18 +12=30
Suppose there are 70 children,then number of children negative for chicken pox =
12/30 x 70 =28
To find the area of a rectangle, we multiply the Base by the Height. In this case the: Base = AB and Height = BC
So to get the area, we multiply AB by BC. (and we know that <em>BC = 5x+5/x+3</em> <em>and BC = [3x+9/2x-4)</em>
So we would do:
x
Note: When multiplying fractions together, we multiply the numerator by the numerator, and the denominator by the denominator.
For example x =
Answer: x =
= [<em>Note: </em><em>we are able to factorise some brackets to make the sum easier. For example we can factor out the 5 in (5x+5) to get: 5(x+1) ]</em>
Now lets simplify by multiplying the 5 and 3 together in the numerator:
=
If you notice, there is a (x+3) in numerator and the denominator. This means that we can cancel out the (x+3), to get the most simplified expression for the area:
=
Final Simplified Answer: which is the last option
|x-4|=1
|x-4|-1=0 absolute values have 2 equations in them
x+4-1=0, x=3
x-4-1=0, x=5
