A literal equation is an equation where the variables represent known values. For example in finding simple interest, the price rate and time are shown by P:price, R:rate, T:time, I:interst, so I=PRT.
Factoring:
FOIL (first, outer, inner, last) method
(a+b)(c+d) = 0
ac+ad+bc+bd = 0
Zeros:
(x+a)(x+b) = 0
x+a = 0, x= 0-a
x+b = 0, x= 0-b
Answer:
(x - 9)(x + 4)
Step-by-step explanation:
x^2−5x−36
As you know, -36 = -9 * 4 and (-9) + 4 = -5
so Factor
= (x - 9)(x + 4)
Answer:
C
Step-by-step explanation:
the range because 18-8 is 10
and the range is the the difference between the smallest number and the biggest number.
