Answer:
1.3
Step-by-step explanation:
Area of a square is side length ^2
To find the length of the side of a square from the area, that’s the square root of the area:
Length of side = sqrt(81) = 9 meters
Area of wall = length of side x height:
Area of wall = 9 x 5 = 45 square meters
Answer: 45 square meters
Expression 1 is the main equation and expression 2 is the more simplified equation from expression 1.
326 + 37g
-287 - 23g
-----------------
38 + 14g
(Though I think 38 is suppose to be 39.)
Answer:
-xy^6 +2y -6
Step-by-step explanation:
(-6x^2 y^8+12xy^3-36xy^2)
-------------------------------------------
6xy^2
Divide each term by 6 in the numerator and denominator
(-6/6x^2 y^8+12/6xy^3-36/6xy^2)
-------------------------------------------
6/6xy^2
-x^2y^8 +2xy^3 -6xy^2
---------------------------------
xy^2
Divide each term by x in the numerator and denominator
-x^2/xy^8 +2x/xy^3 -6x/xy^2
---------------------------------
x/xy^2
-xy^8 +2y^3 -6y^2
---------------------------------
y^2
Divide each term by y^2 in the numerator and denominator
Remember when dividing, we subtract the exponents
-xy^8/y^2 +2y^3/y^2 -6y^2/y^2
---------------------------------
y^2 /y^2
-xy^6 +2y^1 -6
---------------------------------
1
-xy^6 +2y -6
240/6=x
x=40
the number is 40
