Answer:
C
Step-by-step explanation:
to factor x² - x - 2
consider the factors of the constant term which sum to give the coefficient of the x-term.
the factors are - 2 and + 1 since - 2 × 1 = - 2 and - 2 + 1 = - 1
x² - x - 2 = (x - 2)(x + 1), hence (x + 1) is a factor
K(x) = (1/4)^x
(1,4) when x = 1, k(1) = (1/4)^1 = 1/4....FALSE
(3, 1/64) when x = 3, k(3) = (1/4)^3 = 1/64....TRUE
(-1,4) when x = -1, k(-1) = (1/4)^-1 = 4....TRUE
(0, 1/4) when x = 0, k(0) = (1/4)^0 = 1....FALSE
answer
(3, 1/64)
(-1,4)
48" means 48 inches
anyway
the perimiter is the distance around or the sum of the sides
perimiter=48=x+3+4x-1+2x-3=7x-1
48=7x-1
add 1 to both sides
49=7x
divide both sides by 7
7=x
x+3=7+3=10
4x-1=4(7)-1=28-1=27
2x-3=2(7)-3=14-3=11
the sides are 10", 27" and 11"
x=7
