Answer:

11x + 1

Step-by-step explanation:

f(x) = 66x² + 17x + 1

Factoring:

f(x) = (6x + 1) (11x + 1)

Area of a rectangle is width times length.  So if g(x) = 6x + 1, then h(x) = 11x + 1.

Answer:

see explanation

Step-by-step explanation:

(8)

the common ratio r,  of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{a_{3} }{a_{2} } = ......

r = \frac{\frac{1}{32} }{\frac{1}{256} } = \frac{\frac{1}{4} }{\frac{1}{32} } = 8

(9)

The simplest way to evaluate the sum is to substitute k = 3, 4, 5, 6 into each term and sum them

(- 9 + 20) + (- 12 + 20) + (- 15 + 20) + (- 18 + 20)

= 11 + 8 + 5 + 2 = 26

Salsk061 [2.6K]

Answer:

l = 16 feet

Step-by-step explanation:

P = a + b + c + d.

P = 2x + x + 2x + x = 48

6x = 48

x = 48/6

x = 8 feet

Thus, length = 2x = 2(8) = 16 feet

Simplify the expression of (7 – c )(–1)
Ivan
Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c 
thus putting them together to get -7+c which is just c-7
