Answer:
5.4 & 5.4
Step-by-step explanation:
CD²=5²+2²=29
CD=AB=5.4
C) 5.4 and 5.4
CD: 5²+2²=c² = 25+4=c² = 29=c² = c=√29 = 5.4
AB: 5²+2²=c² = 25+4=c² = 29=c² = c=√29 = 5.4
145
m<4 and m<3 would equal 90 so subtract 55 from 90 and you get 35 for m<3 so you subtract 35 from 180 and you get 145
bottom =80m^2
Side =50m^2
triangle = 3 ×8 ×5
y>-4+2x/5
Ok the answer of 6 are 12, 18, 24, 30, 36, 42, and 48. The multiples of 9 are 18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,162,171,180,189,198,. Hope it helps!
5.6x+1.4
(-3.5x+1.7)+(9.1x-0.3)=-3.5x+9.1x+1.7-0.3=5.6x+1.4
