Answer:
the perimeter is 11cm and the area is 7cm^2
Step-by-step explanation:
NP =PS, meaning they have the same length. so the perimeter is 3.5 + 4 + another 3.5.
For the area imagine you cut the triangle in half. from P to the middle of NS. Put the 2 triangle halves together to form a rectangle. (PS is now touching NP). This would be a 2x 3.5 rectangle. 2x 3.5 is 7, meaning both this imagined rectangle and the triangle have an area of 7cm^2.
4/5y + 3(2/5x + 7/5y)...distribute thru the parenthesis
4/5y + 6/5x + 21/5y ...combine like terms
25/5y + 6/5x.....reduce
5y + 6/5x
T= time traveled
M= miles
So if he's traveled the speed limit, which is 75 miles per hour, then you'd multiply that by however long he drove. If he's driven the speed limit, that means he has or is going 75 miles an hour. Wherever he's going, he will be there in an hour if it's 75 miles away. So as a basis, you could use M(t), or 75 times Time. I think.
