Answer:
The answer is 53, C.
Step-by-step explanation:
10 * 5 + 3
50 + 3
53
Pythagorean Theorem: a^2 + b^2 = c^2
-A and B are legs of the triangle
-C is the hypotenuse
#1.
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10
#2.
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
c = 13
#4.
10^2 + 4^2 = c^2
100 + 16 = c^2
116 = c^2
c =
#5.
15^2 + 9^2 = c^2
225 + 81 = c^2
306 = c^2
c =
#6.
120^2 + b^2 = 150^2
14400 + b^2 = 22500
b^2 = 8100
b = 90
#7.
144^2 + b^2 = 194^2
20736 + b^2 = 37636
b^2 = 16900
b = 130
Hope this helps!! :)
The answer is 7/16 because if you turn the denominator into a bigger number so you can get the answer, it becomes 14/16 and half of that is 7/16.
7(3)^2 - 3(3) - 6 = 7*3*3 - 3*3 - 6 = 63 - 9 - 6 = 48
