Answer:
so it would be f=36
Step-by-step explanation:
subtract 4 to the other side then multiply both sides by 3
This would be 198 because 12 times 1.5 equals 18 so when you multiply 132 by 1.5 you get 198
Step1: Find the area of the triangular lawn
Given, base of the triangle is y metres and the height is z metres
Area of the triangle =
2
1
× base × height
Therefore, area of the triangular lawn =

Step 2:Find the cost of planting the grass
Rate of planting the grass is Rs. x per square metre.
Therefore, the cost of planting the grass on a triangular lawn =cost per square meter × area of the triangular lawn
=x×

Answer:
B
Step-by-step explanation:
Given
x² + 3x + 2 = 0
To factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are 2 and 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1
