So for this one all you have to do is use the formular
Z*k=x
30k=8
K=4/15
Then when x=4
4/15x=4
So x=15
Answer:
-24
Step-by-step explanation:

Multiply through by the denominator (that is, 2)


Collect like terms


Divide through by - 5x


The greatest common factor (GCF) is determined by finding the greatest factor that would simplify all the terms of the equation the most.
For the equation -2x³ - 4x² + 4x
The common factor for the coefficients -2, -4 and 4 is -2, since all of them are divisible by -2.
The common factor for the variables x³, x² and x is x, since all of them are divisible by x.
Then, the GCF would be -2x. We use this to simplify the equation:
-2x(x² + 2x -2)
Answer:
180 square inches
Step-by-step explanation:
Area, A is given by A=0.5bh where b is base and h is height. Since both of these dimensions are provided then we substitute the given figures into the formula. Substituting 12 inches for base, b and 30 inches for height, h then the area will be equivalent to
A=0.5*12*30=180 square inches.
Therefore, the area of the described triangle is 180 square inches.
