Answer:

(x-2) (x^2 -5)

Step-by-step explanation:

x^3 − 2x^2 − 5x + 10

We will factor by grouping

Take and x^2 out of the first two terms and -5 out of the last two terms

x^2 (x-2) -5(x-2)

Now we can factor out (x-2)

(x-2) (x^2 -5)

Root of 6x^2 -8 = -8x

Svetlanka [38]

Answer:

If your question is set up like this $\sqrt{6x^2-8}=-8x$ then your answer is No solution.

If your question is set up like this $\sqrt{6x^2}-8=-8x$ then your answer is $x=\frac{4(8-\sqrt{6}) }{29}$ or x = 0.765

Hope this helps!

babunello [35]

Answer:

Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters

The image of the point (-6, -2) under a translation is (-4,2). Find the coordinates of the image of the point (-3, 4) under the

QveST [7]

ANSWER

(-1, 8)

EXPLANATION

First we have to find the rule for this translation.

The image of the x-coordinate of the given point is 2 untis more than the point, so the rule for the horizontal translation is to add 2.

The image of the y-coordinate of the given point is 4 units more than the point, so the rule for the vertical translation is to add 4:

$(x,y)\rightarrow(x+2,y+4)$

Therefore, the image of point (-3, 4) under the same translation is:

$(-3,4)\rightarrow(-3+2,4+4)=(-1,8)$
