I am assuming you are meant to factor this.

Distribute 3x to the parentheses.

3x*-2 = -6x

3x*4x = 12x^2

Put it all together, largest sums first.

12x^2 - 6x

Not sure if they want you to simplify it further by dividing the common factor, but most likely not since you just expanded it. You'd be going backwards if so, and you should challenge your instructor on their logic.

Answer:

B. $6\sqrt2$

Step-by-step explanation:

Given:

The given triangle is an isosceles right angled triangle with the legs equal to 6 cm each and the hypotenuse is 'x' cm.

Applying Pythagoras theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Therefore,

$x^2=6^2+6^2\\x^2=36+36\\x^2=72\\x=\sqrt{72}\\x=\sqrt{36\times 2}\\x=\sqrt{36}\times \sqrt{2}\\x=6\sqrt2\ cm$

Therefore, the length of the hypotenuse is $x=6\sqrt2$ cm.

Hence, the option B is the correct one.

Find the slope and the y-intercept of the graph of the linear equation.<br> y= -3/8x=+10

Y=10
y=-3/(8x) => x=-3/(8y)=-3/80

That doesn't define a slope, that's just one point ...<span />

Which value of x is the solution of the equation 2(x – 4) + 7 = 3? (a) 1 (b) 6 (c) 2 (d) 0

pav-90 [236]

Answer:

Step-by-step explanation:

2(x - 4) + 7 = 3

2x + 2(-4) + 7 = 3

2x - 8 + 7 = 3

2x - 1 = 3

2x - 1 + 1 = 3 + 1

2x = 4

2x/2 = 4/2

x = 2

Hope this helps!!!
