Answer:
W = X in.
L = (3x - 6) in.
A = L*W = (3x-6)X = 45,
3x^2 - 6x = 45
3x(x-2) = 45,
x(x-2) = 15,
x^2 - 2x - 15 = 0
(x-5)(x+3) = 0,
x-5 = 0,
x = 5 in.
x+3 = 0,
x = -3.
Solution Set: x = 5, and x = -3.
Select + value of X:
x = 5
W = x = 5 in.
L = 3x-6 = 3*5 - 6 = 9 in.
Step-by-step explanation:
9^5 is 9*9*9*9*9 you * 9 by how ever many little number there is so you get 59049
and with 9^3 its 9*9*9 729
its NEVER 9*3 or 9*5 you have to times the same number () time the littler number it telling you how many time to do so
Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
0.15 with dash on top and the dash means its a repeating decimal and a repeating decimal is a decimal that repeats itself in this case it would be 0.1515151515 and so on
