The answer is C because when you use the vertical test it only passes through one line
A and B
8/16 = 1/2
A=1/2
B=2/3
C=1/2
D=1
Answer:
4th choice, 20, 21, 29 would be the answer.
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
a= 20, b= 21, c= 29 ( c has to be the C, hypotenuse, because it is the longest)
therefore,
20^2 + 21^2 = 29^2
into
400 + 441 = 841,
which is true, makes the Pythagorean Theorem work.
Answer:
56
Step-by-step explanation:
2a^2b+5ab-4
substitute a & b:
2(-4)^2(5)+5(-4)(5)-4
2(16)(5)+5(-4)(5)-4
160-100-4=56
