Answer:
17.89 ft
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 +16^2 = c^2
64+ 256 = c^2
320 =c^2
Taking the square root of each side
sqrt(320) = sqrt(c^2)
sqrt(64*5) = c
sqrt(64) sqrt(5) =c
8 sqrt(5) = c
17.88854382=c

Answer:
0.27
Step-by-step explanation:
0.72*0.375=0.27
Area = length x width
Perimeter = 2(l + w)
Let's imagine one of the sides is 6. The other side would have to be two, and the perimeter would be 16.
If one of the sides is 4, the perimeter would be 14.
If one of the sides is 1, the perimeter would be 26.
Answer:
-3
Step-by-step explanation:
Expression: |-4| - |7|
1. Absolute value (positive distance from zero; found by removing negative sign unless positive): 4 - 7
2. Subtract: -3
These questions are just a way of saying it's a two system equation. You can go about this by elimination for both of them.
-8x - 4y = -12
+ 6x + 4y = 14
---------------------
-2x = 2
/-2
x=-1
Since A is the only answer with x=-1, you technically don't have to solve for y but it is still a good idea to plug x into one of the equations and solve for y.
2x + 3y = 50
+ 4x -2y = 4
-----------------
multiply the top equation by -2 so you can eliminate your x's
-4x - 6y = -100
+4x - 2y = 4
------------------
-8y = -96
/-8
y=12
Once again, your first answer is the only one with y=12 but you should still go back through and plug things in to double check!
