MrRa [10]
1)B -26-27x
steps :distribute ,-9 times 3 =-27 , -9 times 3x = -27x , now combine like terms :you have a 1 and a -27 ,1-27=-26,and you left with -27



2)D 11-49x
steps :distribute , positive 7 times 1= 7 and then positive 7 times negative 7x =-49, now combine like terms ,since you have a positive 4 combine it with positive 7 which is 11 and finally put it together with -49x which it would look like 11-49x

What is the length of the line segment whose endpoints are A(-1,9) and B(7,4) in the simplest radical form?
monitta

length : \sf \sqrt{89}

Explanation:

use the distance formula : \sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

  • using the formula:

\sf \rightarrow \sf \sf \sqrt{(7--1)^2+(4-9)^2}

\sf \rightarrow \sf \sf \sqrt{(8)^2+(-5)^2}

\sf \rightarrow \sf \sf \sqrt{64+25}

\sf \rightarrow \sf \sf \sqrt{89}
