Answer:
80/8=10 lenght is 10 inches
Step-by-step explanation:
The length is 8, but if you are asking the width it is 10.
You say the length is 8 inches then ask for the length.
If you meant to ask for the width then 80/8=10
evaluate 9(x+3)
expand 9x+27
i think i am sorry if i am wrong
a) As sides of squares are always equal.
So,
BC=CD
2b+CF=a+b
CF= a+b-2b
CF= a-b
b) Area of rectangle CDEF= CDxCF
=(a+b)(a-b)
=(a²-b²)
