Answer: use a standard form calculator
Step-by-step explanation: it helps alot :)
Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
Answer
B. F(x)= x-3/8x
Step-by-step explanation:
A rational function is a function that is a fraction and contains a property that both its numerator and denominator are polynomials.
This is to say F(x) is a rational function if R(x)=p(x)/q(x) where p(x) and q(x) are both polynomials
A polynomial is an algebraic expression which consists of one, two or more terms.
It would be 55.125 as a decimal, but as a fraction it would be 441/8.
Answer:
8+2x and 3(x+4)-(4+x)
Step-by-step explanation:
2(x+4)=2x+8 interchanged to 8+2x
3(x+4)-(4+x) simplified to
3x+12-4-x collect like terms together 3x-x+12-4=2x+8
