-3(x-1)/x would be your answer
Answer:
Kx20=N
Step-by-step explanation:
k with be the number multiplied by 20 and then N will be the answer
15 inches
the formula for the area of a triangle is Area=(1/2)(base)(height)
since the problem is looking for the height, we can rewrite it as
Height=(Area)/((1/2)(Base))
then the number must be substituted in
Height=(187.5)/((1/2)(25))
and the answer is 15 inches.
Answer:
Lesser r = - 7 - √11 or -10.32 to nearest hundredth.
greater r = - 7 + √11 or -3.68 to nearest hundredth.
Step-by-step explanation:
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x + 7 = ±√11.
