Answer:
x = 7, x = -3
Step-by-step explanation:
(x - 2)^2 = 25
Take the square root of each side
sqrt((x - 2)^2) =±sqrt( 25)
x-2 = ±5
Add 2 to each side
x-2+2 = 2±5
x = 2±5
x = 2+5, x=2-5
x = 7, x = -3
Answer:
63.25 sq. ft
Step-by-step explanation:
the area of fig. =
(½×8×6)+(½×3.14×5²)
= 24 + 39.25
= 63.25 sq. ft
Knowing its a geometric sequence, you can divide any number by the one in front of it, the answer is 4.3
Answer:
C. I > 4 (or x > 4)
Step-by-step explanation:
first multiply 8 and (x - 5)
8(x– 5) – 3x > -20 -----> (8 * x) - (8 * 5) = 8x - 40 - 3x > -20
add like terms
8x - 40 - 3x > -20 -----> 8x + -3x = 5x - 40 > -20
combine -40 and - 20
5x - 40 > -20 ----> -20 + 40 = 5x > 20
Then finally divide
5x > 20 -----> (5x/5) > (20/5) = x > 4
