5.
that is square-kite
square=AC^2=(AE+EC)^2=(9+15)^2=24^2=576
kite=1/2 times diagonals=1/2 times AC times BD=1/2 times 24 times (BE+ED)=12 times (7+7)=12 times 14=168
so the shaded area=576-168=408 square inches
6.
trapezoid=(base1+base2) times 1/2 times height
big one is base1=14, base2=25
height =10+12=22
area=(1/2)(14+24)(22)=(11)(38)=418
small one is base1=8
base2=25
height is 10
area=(1/2)(25+10)(10)=(5)(35)=175
so shaded area is 418-175=243 square cm
Answer:
Step-by-step explanation:
-3x(5-4) + 3(x-6)
-15x + 12 + 3x - 18
-15x + 3x +12 - 18
-12x - 6
1km=0.62 miles
so multiply 1km by 5 to get 5km
multiply 0.62 by 5 to get km to miles
0.62 times 5=3.1
answe ris 3.1 miles
For #2 an easier way to solve problems like this is to move the decimal point to the left twice in this case it’ll be 0.15 instead of 15% now you multiply 35 by 0.15 which is 5.25 now you add the total price and the tip 35+5.25=40.25 and there’s your answer
