Answer:
Length of garden will be 30 metres.
Step-by-step explanation:
Let the Width of garden be x metres.
then,
Length of garden will be (x+6) metres.
Area = Length × Breadth
720 = x X (c+6)
720 = x²+6x
0 = x²+6x-720
As we can see above equation is a quadratic equation in the form of ax²+bx+C.
so,
One of the Roots of the Quadratic equation is 24 and other is -30.
And as we know width of any garden cannot be negative so the width of garden will be 24 metres.
As we got the width,
adding 6 to it will give us the Length,
So,
24 metres + 6 = 30 metres.
Length of the garden is 30 metres.
Hope It Helped You ;)

Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
The given expression is a (A) linear expression.

What are linear expressions?</h3>
- A linear expression is an algebraic expression in which each term is a constant or a variable raised to the first power.
- To put it another way, none of the exponents may be greater than 1. x2 is a variable raised to the second power, whereas x is a variable raised to the first power.
- A constant is represented by the number 5.
- Reduce the equation as much as feasible to the form y = mx + b. Examine your equation for exponents.
- It is nonlinear if it has exponents. Your equation is linear if it contains no exponents.
- 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x - y + z = 3 are some instances of linear equations.
Therefore, the given expression is a (A) linear expression.

Answer:
9 years = 12 grams
Step-by-step explanation:
0 years = 96 grams
After 3 years , the amount left is 1/2 of what you started with
3 years = 1/2 *96 = 48 grams
After 3 years , the amount left is 1/2
6 years = 1/2 (48) = 24 grams
After 3 years , the amount left is 1/2
9 years = 1/2 ( 24) = 12 grams
