2(x-2)=6
2x-4=6
2x=6+4
2x/2=10/2
x=5
Answer:
300 Square feet
Step-by-step explanation:
Susan built a rectangular fence around her swimming pool.
Length=15ft
Width(or Breadth)=10ft
Height=6ft
To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.
Surface Area of a Cuboid= 2(LW+LH+WH)
However since the top and bottom are open, the Surface Area becomes
Surface Area of the fence= 2(LW+WH)
=2((15X6)+(10X6)
=2(90+60)=2 X 150 =300
Susan uses 300 Square feet to build her fence.
Answer:
-17x - 27
Step-by-step explanation:
Distributive property is the multiplication of the number outside the parenthesis and the ones inside.
-5(x + 4) + -3x + -9x + -7
-5x - 20 + -3x + -9x + -7
Combine like terms:
-5x - 20 + -3x + -9x + -7
-5x +-3x
-8x + -9x
-17x
-17x - 20 + -7
-20 + -7
-27
The answer is -17x - 27
Hope this helped.
Irrational would be the correct answer
