Answer:
width=3
Step-by-step explanation:
area=length X width
length=4 X width
=>area=4 X width X width
=>area=(2 X width)^2
=>36=(2 X width)^2
=>6=2 X width
=>width=3
<em>the area of a rectangle is length times width </em>
<em> A = L times W</em>
<em> A = 26. so 36 = L times W </em>
<em>The length is 4 times the width </em>
<em>L = 4W </em>
<em>Thus, we can switch L to 4W in the area equation </em>
<em>36 = 4W ×W = 4W²</em>
<em>36 ÷ 4</em>
<em>=√9</em>
<em>=3cm</em>
9. 1/18
10. 1/18
<u>Here is how I got my answer for 9:</u>
Step 1: Simply to . Which leaves us with -
Step 2: Find the least common denominator, which is 18.
Step 3: Make the denominators the same as the least common denominator. By multiplying and . Which leaves us with - .
Step 4: Subtract 3 and two, giving you your answer:
<u>Here is how I got my answer for 10:</u>
Step 1: Simplify to . Which leaves us with -
Step 3: Make the denominators the same as the least common denominator by multiplying and . Which leaves us with .
Step 4: Subtract 9 and 8, giving you your answer:
B
dividing with the same numbers and different exponents is like subtracting the exponents
16-8 = 8
