For this, we can say they are similar and proportional to one another. If they are and the perimeter of the smaller figure is 7.3, we can find the perimeter of the larger figure by .....
7.3 ÷ 1.75 = 4.17..... then multiply this by the outside figure's side
4.17.... × 3.5 = 14.595 ... or 14.6
or
3.5 / 1.75 = gives us a dilation of 2.....so we can multiply 2 x 7.3 = 14.6
Answer:
460
Step-by-step explanation:
919 ÷2 = 459.5 so you have to round to the nearest hole so when its 5 or more you round up to the nearest whole and when its 4 or less you round down so your answer is 460
5x^2+3x-4=0
<span>x^2+3x/5-4/5=0 </span>
<span>x^2+3x/5=4/5 </span>
<span>x^2+3x/5+9/100=89/100 </span>
<span>(x+3/10)^2=89/100 </span>
<span>x+3/10=±(√89)/10 </span>
<span>x=-3/10±√89/100 </span>
<span>x=-3±(√89/10)</span>
The answer to part A would be 1.32 inches! :)
Have a very Merry Christmas if you celebrate it!!!
Ya if it was just 18-6 that would be 12 and 3+2 equals 5
