1. Write the factors
(x+3)(x-6) = 0
2. Multiply the factors to get the answer in standard form
x^2 + 3x - 6x - 18 = 0
3. Simplify
x^2 - 3x - 18 = 0
Answer:
648 sq units
Step-by-step explanation:
Area of the base= 12×12= 144 sq. units
Perimeter of the base=4×12= 48
Total surface area= 1/2×48×21 + 144
=648 sq units
Answer:
The value of this new equation would be (2x - 5)/6x.
Step-by-step explanation:
In order to find the value of this equation, we need to take the original equation and replace every x with (x - 1/x+2).
f(x)= 3x - 1/4x + 2
f(x)= [3(x - 1/x+2) - 1]/[4(x - 1/x+2) + 2]
f(x) = [(3x - 3/x + 2) - (x + 2/x + 2)]/[(4x - 4/x + 2) + (2x + 4/x + 2)]
f(x) = (2x - 5/x+2)/(6x/x + 2)
f(x) = (2x - 5)/6x
Answer:
1/2
Step-by-step explanation:
The red markings is not clear but I think the larger one is triangle DEF, if not, then the answer is 2
