We don't not know what would x really equal. So when solving this, it would look like the problem would be not quite finished, but it would be, so we would be subtracting this, but keeping x as it's self.

Let's talk x out of the whole problem.

(4-12) = 8. This would be the answer so far.

Then we do, (8-18) = 10.

Now we can bring x back in the problem.

Your answer would be (10x).

Factorise 8a^3+b^3+12a^2b+6ab^2​
Sholpan [36]
Answer: See below

Explanation:

8a^3+b^3+12a^2b+6ab^2
= (8a^3+b^3) + (12a^2b+6ab^2)

= (2a+b)(4a^2+2ab+b^2)+6ab(2a+b)
= (2a+b)(4a^2+2ab+b^2)+6ab
= (2a+b)(4a^2 + 2ab+b^2+6ab)
= (2a+b)(4a^2+8ab+b^2)

Complete the equation of the line whose slope is -2 and y intercept is (0,3).
rosijanka [135]

Answer:

y= -2x+3

Step-by-step explanation:

The equation of a line is written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Given that the slope is -2, m= -2.

Y-intercept is at 3 so c=3.

Thus, the equation of the line is y= -2x +3

CAN SOMEONE PLEASE HELP ME RIGHT NOW.
exis [7]

Answer:

m∠SRV = 48°

Step-by-step explanation:

In the parallelogram attached,

m∠TUV = 78°

m∠TVU = 54°

By applying the property of the angles of a triangle in ΔTVU,

m∠TUV + m∠TVU + m∠UTV = 180°

78° + 54° + m∠UTV = 180°

m∠UTV = 180° - 132°

             = 48°

Sides RS and TU are the parallel sides of the parallelogram and diagonal TR is a transverse.

Therefore, ∠UTV ≅ ∠SRV [Alternate interior angles]

m∠UTV = m∠SRV = 48°
