Answer:
C
Step-by-step explanation:
Jar 1 : 16 red, 4 blue....total = 20
P(blue) = 4/20 reduces to 1/5
jar 2 : 75 white,25 blue...total = 100
P(blue) = 25/100 reduces to 1/4
P(blue,blue) = 1/5 * 1/4 = 1/20 or 0.05 or 5%
I’m not sure about the estimates but the overall answers should be correct
Answer:
area (A) =(9x+108)unit^2
perimeter (P) =(2x+42) units
Step-by-step explanation:
area(A) =length(l) × breadth(b)
perimeter(P) =2(l+ b) {which is sum of all sides}
so, l = 7+x+5 = (x+12) units and b = 9 units
now, A=(x+12) × 9 units^2
=(9×x + 12×9 ) units^2
Therefore,
A =(9x+108)unit^2
next, P=2{(x+12)+9}
=2(x+21)
Hence,
P=(2x+42) units
