4. C)If two figures are congruent, then they are similar.
If they are congruent them shape and size are the same and hence they are similar
5. Ratio 4/3 smaller side is 21
Multiply to find large side
4/3×21= 28ft D)
6. Width went from 24 to 3 in divide to get ratio
24/3 =8 now divide the length by 8 to find the postcard length
32/8= 4 in A)
8. If they are similar you need to find the ratio y reduces from 8 is similar to 6 so link those 6/8
This is your ratio you can simplify it to 3/4 now y/6 should also = 3/4
Y/6=3/4
Y=18/4= 4.5 C)
9.C)DC

The ratio is width over length.
Make a fraction with the width on top and the length on the bottom:
44/70
Both numbers are even and can be divided by 2,
so the simplified fraction becomes 22/35
Answer:
option C.(4x+5)(4x-5)
Step-by-step explanation:
root of 16x^2 is 4x and 25 is 5
apply identity (a+b)(a-b)=a^2-b^2
so, (4x+5)(4x-5)
