Answer:
4x^2 +9xy +6y^2
Step-by-step explanation:
Combine like terms. I find it useful to factor out the variable part of the expression so I can see what coefficients are being combined.
7x^2+5xy-3y^2 - (2x^2+3xy-5y^2 + x^2-7xy-4y^2)
= (7 -2 -1)x^2 +(5 -3+7)xy +(-3 +5 +4)y^2
= 4x^2 +9xy +6y^2
Answer:
x ≤ -15
Step-by-step explanation:
-x / 3 ≥ 5
multiply by 3
-x ≥ 15
add x to both sides and subtract 15 from both sides
-15 ≥ x or x ≤ -15
Answer:
The length of the fence is 38 yards
These are the expressions
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, a rectangle.
The length of the fence is the perimeter of the garden which is the expression that Chole could use
1. Perimeter = 2l+ 2w
2. Perimeter = 2(l+w)
Given data
Length = 11 yards
Width = 8 yards
Perimeter = 2(11)+ 2(8)
Perimeter = 22+16
Perimeter = 38 yards
Answer: The actual price of house sold at $109000.
Step-by-step explanation:
Since we have given that
Selling price = $100000
Rate of commission = 7%
So, Amount of commission would be

Total commission = $7540
So, Remaining amount of commission would be

Rate of commission exceeding $100000 = 6%
Let the selling price of house be 'x'.
According to question,

Hence, the actual price of house sold at
$100000+$9000=$109000.
Answer:
x=-6
Step-by-step explanation:
-4x-2=22
Add two on both sides
-4x(-2+2)=22+2
-4x=24
Divide by negative 4
-4x/-4x=24/-4
Answer:
x=-6
