Answer:

look I dont know the answer

Step-by-step explanation:

but look their is an aapp called MATH installed it and w you will get the answer
4. a) the sum of 30 and 100 is 130
100+30=130
$99. 100%
$X. 130%
X=99•130/100
X=12870/100
X=128.70$


4 b) If X is increased price
99•(130:100)=X
99•1.3=X
Equality:
99•(130:100)=99•1.3
99•1.3=99•1.3

5
a) AB=8X
Reduction of 40%
40%=4/10=2/5
AB’ =8X•2/5
AB’=16X/5

b) AC=6X
AC’ =6X•2/5
AC’=12X/5

c) CB? Can’t see the vector
CB= 2X+10
CB’ = 2X+10•2/5
CB’ = 2(2X+10)/5
CB’ = 4X+20/5

d) P of reduced triangle
P’ = AB’ + AC’ + CB’
P’ = 16X/5+12X/5+4X+20/5 all sides have same denominator of 5 therefore we can add them up,
P’ = 16X+12X+4X+20 all over 5
P’ = 32X+20/5=4(8X+5)/5

Good luck.
