Answer:
Yes, all your answers are correct.
They are correctly matched with their reasons.
Half of 3600 ft^2 is 1800 ft^2 and 2/5 of 3600 ft ^2 is 1440 ft^2 so 1800 plus 1440 is 3240 ft^2 so 3240 ft^2 of the yard is now mowed
(12 + 7x)(12 - 7x) the answer to the question
145, you subtract the total number with how many you sold
523-378=145
Answer:
<h2> 8.06ft</h2>
Step-by-step explanation:
step one:
This problem is on the mensuration of solids,
given that the area is 65ft^2
step two:
we know that the expression for the area of a solid is
areaa= length* length
area= l^2
step three:
substituting the value of the area into the expression we have
65=l^2
we need to square both sides to solve for l we have
√65=l
l= 8.05ft
step four:
From the analysis we found the length of one side to be 8.06ft
