Answer:
B
Step-by-step explanation:
hope this helps with the work
The length of the shortest piece is 5cm.
Given that the length of the board = 62cm
Let the length of the first piece be x cm.
Hence, according to the question,
Length of the second piece = 2x cm
Length of the third piece = (2x + 7) cm
We have to find the length of the shortest piece.
Hence, we can write,
62 = x + 2x + (2x + 7)
62 = 5x + 7
5x = 62 - 7 =55
x = 55/11 = 5 cm
Hence, the shortest side is the first side of 5 cm.

Answer:
Step-by-step explanation:
Area of rectangle = 4 cm × 9 cm = 36 cm²
Side of square = √(36 cm²) = 6 cm
It is calculations because with measurements you would just put a decimal. The calculator uses improper fractions.
<span>6●7–5x+<span>x2</span>≥<span>x3</span>+<span>x2</span></span>
Lets plug in 3:
<span>6●7–5(3)+<span>32</span>≥<span>33</span>+<span>32</span></span>
Multiply -5 * 3:
<span>6●7–15+<span>32</span>≥<span>33</span>+<span>32</span></span>
Simplify all exponents:
<span>6●7–15+9≥27+9</span>
Multiply 6 * 7:
<span>42–15+9≥27+9</span>
Subtract 42 - 15:
<span>27+9≥27+9</span>
Add 27 + 9:
<span>36≥27+9</span>
Add 27 + 9:
<span>36≥36</span><span>
So 3 is correct.</span>
