(3a-7)^2
1. 9a^2-21a-21a+49
2. 3a(3a-7)-7(3a-7)
3. (3a-7)(3a-7)
4. Combine like terms
Answer:
z=44/3
Step-by-step
Subtract the numbers 52-12=40
3z-4=40
Add 4 to both sides
3z-4+4=40+4
SImplify
3z=44
Divide both sides by 3
3z/3 = 44/3
z=44/3 or decimal form= 14.66
Answer:
For not exact divisions: Writing the results as Quotient + Remainder over the Divisor.
For exact division: just the quotient.
Step-by-step explanation:
Hi there,
In both algorithms, for long and synthetic divisions we must write the result as an expression following that order:

When the Division leaves no Remainder, i.e. an exact, the Remainder is equal to zero, so

Check below for the algorithms for each division and the way of writing their expressions (results).
Answer:
8^2 ft^2
Step-by-step explanation:
8^2= 64, and to find area it lengthxwidth.
so 8x8=64
