Answer:
b) 24 rows
Step-by-step explanation:
12 inches = 1 foot
Since we are doing 30 feet, multiply 12 by 30
12 · 30 = 360 inches
Then, divide the total length (360 inches) by the spacing size (15 inches)
360 ÷ 15 = 24 rows total
Answer:
876/7
Step-by-step explanation:
Just plug the number 5 into the equation and solve. Remember your Order of Operations (PEMDAS).
Answer:
A=z
B=-2
C=0
D=30
Step-by-step explanation:
First lets simply the equation
21 - (2x +3)2 + 4(1-1) + z^3
21 - (2x^2 + 9) + 4(0) + z ^3
21 - 2x^2 + 9 + z^3
- 2x^2 + z ^3 + 30
This means that:
A=z
B=-2
C=0
D=30
(4ab - 9a - 8) - (7ab - 1)
distribute (multiply) the negative through the parenthesis
<span>(4ab - 9a - 8) - 7ab + 1
No need for other parenthesis because nothing in front or to combine inside. </span>
<span>4ab - 9a - 8 - 7ab + 1
</span>
Combine like terms
- 3ab - 9a - 7
