Answer:
C. 6
Step-by-step explanation:
It is given that the rectangles in the figure are similar.
<em>Thus, the corresponding sides of the two rectangles will be equal.</em>
So, we get,

i.e. 
i.e. 
i.e. 
i.e. x = 6.
Hence, the value of x is 6.
Answer:
9
Step-by-step explanation:
KL + KJ = 17
2 + 3x + 5x - 1 = 17 add like terms
8x + 1 = 17 subtract 1 from both sides
8x = 16 divide both sides by 8
x = 2
KL = 5x - 1 replace x with 2
5*2 - 1 = 9
Answer:
x= 2
z=117
Step-by-step explanation:
To find x:
63=(6x+51)
Simplify/ Subtraction property
12=6x
Evaluate/ division property
2=x
To find z:
Subtract 180 and 63 to get 117
F(4) = 7+4(4-1)
f(4) = 7+4(3)
f(4) = 7+12
f(4) = 19
The forth term is 19
f(40) = 7+4(40-1)
f(40) = 7+4(39)
f(40) = 7+156
f(40) = 163
The fortieth term is 163
