What is the factored form of the polynomial?

Mathematics
1 answer:
Firdavs [7]3 years ago
8 0

Answer:

(x-3) (x-9) or (x-9) (x-3)

Step-by-step explanation:

1) what * what=27

and what+what=-12

factors of 27: 9,3  -9,-3  1,27 -1,27

-9+-3=-12

hence -9 and -3 are our factors

(substitute -9 and -3 in place of -12)

x^2-9x-3x+27

split into two groups:

x^2-9x

(both have a gcf of x)

x(x-9)

and

-3x+27

(both have a gcf of "-3"

-3(x-9)

take the numbers OUTSIDE the parantheses and put them in a bracket:

(x-3) (x-9)

Hope this helps!

1. 2 (2x +1) + x = x + 2x + 18<br> 2. 2x + x + 2x = 10 + x
GuDViN [60]

Answer:

1: X= 8, 2: 2/5 or 0.4

Step-by-step explanation:

1: 2(2x + 1) + x = x + 2x + 18

5x + 2 = 3x + 18

2x = 16

x = 8

2: 2x + x + 2x = 10 + x

5x = 10 + x

4x = 10

x = 4/10

x = 2/5

x = 0.4

A ball is thrown straight up from the top of a building 144 ft tall with an initial velocity of 48 ft per second. The height
fgiga [73]

Answer:

180feet

Step-by-step explanation:

Given the function that models the height of a ball

s(t) = 144 + 48t − 16t^2.

At maximum height, the velocity is zero ie. ds/dt  = 0

ds/dt = 48 - 32t

0 = 48 - 32t

48 = 32t

t = 48/32

t = 1.5secs

Get the maximum height

s(t) = 144 + 48t − 16t^2.

s(1.5) = 144 + 48(1.5)-16(1.5)^2

s()1.5) = 144 + 72 - 16(2.25)

s(1.5) = 144 + 72-36

s(1.5) = 180 feet

Hence the maximum height attained by the ball is 180feet

The measure of two complementary angles are in the ratio 1 : 5. What are the degree measures of the two angles? What is the solu
ser-zykov [4K]
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees

1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75

so ur 2 angles are : 15 and 75
