Answer:

B

Step-by-step explanation:

Given

(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1

= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms

= x² - 7x + 4 → B

Step-by-step explanation:

(4 {x}^{2}  - 3x - 4) - (3 {x}^{2}  + 4x - 8) \\  \\  = 4 {x}^{2}  - 3x - 4 - 3 {x}^{2}  - 4x + 8 \\  \\  = 4 {x}^{2}  - 3 {x}^{2}  - 3x - 4x - 4 + 8 \\  \\  =  {x}^{2}  - 7x + 4

Thus option B is the correct answer.

What is the simplified form of ? 12x6 12x18 72x6 72x18
andreev551 [17]

Answer:

12*x^18

Step-by-step explanation:

144=(2^4)*(3^2)

then

sqrt (144 x^36)=sqrt (144)*sqrt (x^36) 

sqrt (144)=sqrt ((2^4)*(3^2))=2² * 3=12

sqrt (x^36) =x^(36/2)=x^18

therefore

sqrt (144 x^36)=sqrt (144)*sqrt (x^36)=12*x^18

the answer is 12*x^18

At a summer camp there is one counselor for every 5 campers. Determine whether there is a direct variation between the number of
adell [148]
Campers = y and counselors = x.....1 counselor to 5 campers

y = kx
k = y/x
k = 5/1

y = 5x

lets check..
y = 5x....lets say u have 2 counselors...sub in 2 for x
y = 5(2)
y = 10....so when there is 2 counselors, there are 10 campers

y = 5x...lets say u have 3 counselors...sub in 3 for x
y = 5(3)
y = 15...so when there are 3 counselors, there are 15 campers

2/10 reduces to 1/5
3/15 reduces to 1/5

so yes, this is a direct variation with ur equation being y = 5x

Please help...
alexandr402 [8]

Sure.  From those choices, the only one that makes sense is that he
didn't perform enough trials.  Technically, you can't expect the experimental
probability to match the theoretical probability until you've rolled it an infinite
number of times.

I have a hunch that even for only 60 trials, such a great discrepancy between
theory and experiment is beginning to suggest that the cubie is loaded.  But
you really can't say.  You just have to keep trying and watch how the numbers
add up.

Find the shaded angle
masya89 [10]

Answer:

332°

Step-by-step explanation:

Given is an isosceles triangle,

Measures of base angles of an isosceles triangle are equal.

Therefore,

Measure of central angle

= 180° - ( 76° + 76°)

= 180° - 152°

= 28°

Measure of shaded angle

= 360° - 28°

= 332°

A shop owner offered a 20%discount off the regular price of a mirror.The amount of the discount is $3.00
Scrat [10]

Answer:

A) $15

Step-by-step explanation:

let x represent the regular price of the mirror

so, 20% of x = 3

20/100 * x = 3

20x = 300

x = 300/20

x = 15

Hence, the regular price of the mirror is $15
