Part 1:
We are going to divide.
18 ÷ 2/5
18/1 * 5/2
90/2
[ 45 pieces ] can be cut.
Part 2:
We are going to divide.
5 1/5 ÷ 1 4/10
26/5 ÷ 14/10
26/5 * 10/14
260/70
3.7
Note that we need FULL pieces so we are going to round down.
3.7 -> 3
Therefore, the answer is [ B.) 3 ]
Best of Luck!

We need to perform division of polynomials such as the solution is shown below:
( 32x8 - 8x6 + 28x4) / 4x4
(32x8 / 4x4) - ( 8x6 / 4x4 ) + (28x4 / 4x4)
8x4 - 2x2 + 7
The power of the result was already arranged in descending order.
The answer is "8x4 - 2x2 + 7 ".
Answer:
Using the height theorem:
![n^2=8*4=32=>n=4\sqrt{2}](https://tex.z-dn.net/?f=n%5E2%3D8%2A4%3D32%3D%3En%3D4%5Csqrt%7B2%7D)
Now we can easily use the pythagorean theorem:
![8^2+(4\sqrt{2})^2 =64+32=96=>m=\sqrt{96} =4\sqrt{6}](https://tex.z-dn.net/?f=8%5E2%2B%284%5Csqrt%7B2%7D%29%5E2%20%3D64%2B32%3D96%3D%3Em%3D%5Csqrt%7B96%7D%20%3D4%5Csqrt%7B6%7D)
Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides
