Answer:
10 or 4.
Step-by-step explanation:
[(x - 7)^2 + 6 - 13 ] * 4 - 1 = 7
(x^2 - 14x + 49 - 7) * 4 - 1 = 7
4x^2 - 56x + 196 - 28 - 1 - 7 = 0
4x^2 - 56x + 160 = 0
4(x^2 - 14x + 40) = 0
(x - 10)(x - 4) = 0
x = 10 , 4
The formula is
A=p (1+r)^t
A=20×(1+0.5)^(12)
A=2,594.9 round your answer to get
A=2595
Answer:
7.74cm ^2
Step-by-step explanation:
a=pie * r ^2
3.14*3^2=3.14*9=28.26 then you know all sides of a square are equal and 3 is half of 1 side so 6*6-=36 36-28.26=7.74
