From the first 2 statements again , x + 8 = y.
area of the hole would be 4x cm^2
area of sheet without hole is 9y cm^2
9y - 4x =76 ------------- eqn one
y = x + 8 ----------------eqn two
subs eqn two into one and u got it
btw what questions are these :o
<span>A-2b=2
A-b=6
</span>
<span>A-2b=2
-2(A-b=6)
-2A+2b= -12
A-2b=2
-2A+2b = -12
-------------------
-A = -10
-A/-1 = -10/-1
A = 10
a-b=6
10 - b = 6
10-10-b = 6 -10
-b = -4
-b/-1 = 14/-1
b= 4
Check
a - 2b =2
10 - 2(4) =2
10 - 8 = 2
2=2

Answer:
Addition is...
1+1 = 2
But addition irrational numbers is...
π + 5 normally when using pi (π) the numbers are 3.14 but the number is infinite, all irrational numbers are infinite
then the sum will be 3.14 + 5 = 8.14
-1/8(x + 35)= -7
Use distributive property(Multiply -1/8 by x and 35)
-1/8x - 35/8= -7
Add 35/8 to both sides.
-1/8x= -21/8
Divide -1/8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: 1/21
Slope is -3/4
