2 answers:

7 0

Simplify: 12(2 + 3x - 6)
= (12)(2 + 3x + - 6) = (12)(2) + (12)(3x) + (12)( - 6)
= 24 + 36x - 72
Answer = 36x - 48

2: Factor:

36x - 48
= 12(3x -4)

Answer
= 12(3x -4)

3: <span>12(2+3x−6)

= 12(3x + 2 - 6)

= 12(3x - 4)

Your Answer would be (A).

3x - 4</span>

On a balanced scale are a 25-g mass, a 100-g mass, and five identical blocks marked X as shown. What is the mass of each block m

expeople1 [14]

Answer:

One block - 15

Two blocks - 30

Three blocks - 45

Four blocks - 60

Five blocks - 75

Equation: 25 + 5x = 100

Step-by-step explanation:

This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:

25 + 5x = 100.

(We have the 5x because we have 5 blocks that are marked as x)

subtract 25 from both sides

25-25 + 5x = 100-25

5x = 75

the following step is to divide both sides by 5.

5x/5 = 75/5

x = 15

Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.

(All five of them equal 75-g)

I need 4 more tryna go to sleep rn :/

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

It is $y=2x+2$ because you should use $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ then just plug it in using

(1, 4) and (-2, -2).

$\frac{4--2}{1--2} =\frac{6}{3} =2$

That eliminates everything except the second one and the third.

So now we would find the b in the equation $y=mx+b$

$y=mx+b\\4=2(1)+b\\4=2+b\\2=b\\b=2$

and that's all

Convert 166.47 ft2 to square inches

Vesnalui [34]

It is important when converting from square feet to square inches to remember to multiply twice. 166.47 times 12 times 12.
Therefore the solution is 23971.68 square inches.

Given the functions f(x) = 6x 11 and g(x) = x2 6, which of the following functions represents f[g(x)] correctly? f[g(x)] = 36x2

ra1l [238]

Function defines relationship between variables. The value of the f[g(x)] when the value of f(x)=6x+11 and g(x)=x²+6 is f[g(x)]= 36x²+47.

<h3>What is a function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given to us

f(x) = 6x + 11

g(x) = x² + 6

As we know the two functions, given to us f(x) = 6x + 11, therefore substitute the value of x as g(x) in order to find the value of f[g(x)] ,

$f(x) = 6x + 11\\\\f[g(x)] = 6(x^2 + 6) + 11\\\\f[g(x)] = 6x^2 + 36 + 11\\\\f[g(x)] = 6x^2 + 47$

Hence, the value of the f[g(x)] when the value of f(x)=6x+11 and

g(x)=x²+6 is f[g(x)]= 36x²+47.
