ANSWER:

[8] By intersecting secant theorem,

x + 27 = 9 + 21
x + 27 = 30
x = 30 – 27
x = 3

[9] By intersecting secant theorem,

7x + 2 + 18 = 6x + 3 + 20
7x + 20 = 6x + 23
7x – 6x = 23 – 20
x = 3

[10] By secant property,

x + 7 = 13 + 8
x + 7 = 21
x = 21 – 7
x = 14

Answer:

f(x) = 2+√x

Step-by-step explanation:

To shift a function up by k units, add k to the value of the function. Here, you want to shift the square root function up 2 units, so you add 2 to the square root:

f(x) = 2+√x

The area of a rectangular closet is 8 square feet. The perimeter is 12 feet. What are the

3241004551 [841]

A=8ft^2
A=l•w
8=l•w
l=8/w

P=2(l+w)
12=2(8/w+w)
12=2(8/w+w/1)
12=2(8/w+w^2/w)
12=16w^2/w
12=16w
w=12/16
w=3/4=0.75ft
l=8/0.75=10.67ft
