Answer:
93 pieces
Step-by-step explanation:
To cover his backyard with sod, he needs to cover the area of the backyard.
His backyard is a rectangle, and area of a rectangle is given as:
Where,
is the length, and
is the width
So, the area of Jim's backyard is 
square yards.
The area of each sods are solved using the area of the rectangle formula. So we have 
square yards as the area of each sod.
<em>To find </em><em>HOW MANY</em><em> of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:</em>
<em>
</em>
<u>Since, fractional sods can't be bought, Jim has to buy </u><u>93 sods</u><u> to cover his backyard.</u>
Answer:
k=2
Step-by-step explanation:
7[k+8]=70
First distribute the 7 into the k+8
7k+56=70
Then subtract the 56 on both sides since we want to isolate the variable
7k=14
Lastly divide each side by 7 to get the variable by itself and its value
k=2
We can check this by plugging 2 into the equation. We substitute for 2 in place of k.
7[2+8]=70
First do inside the brackets
7[10]=70
Next multiply
70=70
The equation is true so we know for sure that 2=k
I’m guessing they are the same shaped, just enlarged. So all you gotta do if so is 18/10 which gives you 1.8 and then 7 x 1.8, this will give you 12.6
So the answer is 12.6, sorry if I’m wrong
