Answer:
AB = 2.25
Step-by-step explanation:
Perimeter of square = 4L
24 = 4L
L = 24/4
L = 6cm
Hence the side length of square is 6cm
Area of square = L^2
Area of square = 6^2
Area of square = 36 sq. cm
Area of square = 1/2 * Area of the trapezium
36 = 1/2 * (AB+3AB)*8
72 = (AB+3AB)*8
72 = 4AB * 8
72 = 32AB
AB = 72/32
AB = 2.25
Answer:
d=-18
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Each time Ryan flips the coin, he has 2 possibilities: heads (H) or tails (T).
Since Ryan flips the coin 3 times, we just multiply 2 by itself thrice:
2 * 2 * 2 = 8
Thus, there are 8 possible combinations.
Hope this helps!
Answer: y=17-5x/-9
Step-by-step explanation: 5x-9y=17
-9y=17-5x
Y=17-5x/-9
You can’t go any further than that because you can’t combine unlike Terms on the right side of the equation.
Answer: 
Step-by-step explanation:
In this case we know that the legs of the given right triangle have these lenghts:
and 
By definition, the sides of a right triangle are in the ratio 
Since:
We can multiply the lenght by 1.25 in order to find the lenght of the hypotenuse of the right triangle:
Since the perimeter of a triangle is the sum of the lenghts of its sides, we can write the following expression for the perimeter of the given right triangle:
Simplifying, we get:
