You most likely have to multiply 10 (7 times) and whatever your answer is then you multiply your answer times 64
<span>x+2y=11
can be written as
x = 11 - 2y
substitute x into the other equation
</span>-8(11 - 2y) + 6y=22
<span>simplify
-88 + 16y + 6y = 22
-88 + 22y = 22
+88 +88 isolate y
22y = 110
----- -----
22 22
y = 5! now add Y into the equation to find X
</span>-8x+6(5)=22
<span>-8x+30=22
- 30 -30
-8x = -8
---- ----
-8 -8
x = 1 (1,5) Is the solution

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
The value of x is 4
Hope this helps
