Answer:

-2x2a • (2x2 + 4b - 5)

Step-by-step explanation:

Step by step solution :

Step 1 :

Equation at the end of step 1 :

2xa • ((-4xb - 2x3) + 5x)

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

-2x3 - 4xb + 5x = -x • (2x2 + 4b - 5)

Trying to factor a multi variable polynomial :

3.2 Factoring 2x2 + 4b - 5

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Multiplying exponential expressions :

3.3 x1 multiplied by x1 = x(1 + 1) = x2

Final result :

-2x2a • (2x2 + 4b - 5)

if he allows 40 people to choose a treat from the bag about how many lizard lollis can he expect to give away

kirill [66]

Answer:

20 Lizard lollies.

Step-by-step explanation:

There are 10 lizard lollis. This is out of 10+4+6 = 20 total treats. This makes the probability of drawing a lizard lollis 10/20 = 1/2.

This means out of 40 treats handed out, we can expect him to give out 1/2(40) = 20 lizard lollis.

Find the unknown length of the right triangle. If necessary approximate the length to the nearest thousandth

WARRIOR [948]

We are given a right triangle and we are asked to determine the hypotenuse given the measure of its sides. To do that we will use the Pythagorean theorem:

$h^2=(10km)^2+(20km)^2$

Now, we solve the square:

$h^2=100km^2+400km^2$

Now, we add the values:

$h^2=500km^2$

Now, we take the square root to both sides:

$h=\sqrt[]{500km^2}$

Solving the operations:

$h=22.361km$

Therefore, the length of the hypotenuse is 22.361 kilometers.
