Answer:
B.
Step-by-step explanation:
3 x 7 = 21, so it is B. You can't multiply 3 by anything to get the other numbers.
Let the lengths of EH and FG = x
Let the lengths of EF and HG = x-5
Solve,
X + X + (X-5) + (X-5) = 48
4X - 10 = 48
4X = 58
X = 14.5
EH= 14.5
FG = 14.5
EF = 9.5
HG = 9.5
Answer:
a=12
Step-by-step explanation:
a/40=3/10
10 x 4=40, so
3 x 4=12
a=12
Answer:
(3,10)
Step-by-step explanation:
From f(x)=10 you can see that the value of y,which is equal to f(x), is 10.
Therefore, the only option you could pick is that where y=10,which is the case for option (3,10).
