Stressful finals week. I'm doing a practice test for my final tomorrow, and I'm stuck on these problems. i'd appreciate it if any of you could help out?
1.) A rectangular garden has dimensions of 15 by 10 feet. A gravel path of equal width is to be built around the garden. How wide can the path be if there is enough gravel for 350 feet?
A.) 5 ft
B.) 6 ft
C.) 7.5 ft
D.) 7 ft
2.) A lot is in the shape of a right triangle. The shorter leg measures 90 m. The hypotenuse is 30 m longer than the length of the longer leg. How long is the longer leg?
A.) 150 m
B.) 180 m
C.) 120 m
D.) 90 m
3.) Solve the equation:
(-7 / m - 3) - (2 / m + 3) = 3 / m^2 - 9
A.) -2
B.) Square Root Sign 8
C.) 2
D.) No Solution
LAST ONE
4.) Find the ordered pair for the vertex
y = 3x^2 + 24x + 50
A.) (4, -2)
B.) (-4, 2)
C.) (2, -4)
D.) (-2, 4)
Thank you so much for the help. Whoever it is! Very much appreciated!
