(4a³ + 7a²b + 6b³) + (a³ + 2a²b + 4b³)

Get rid of the parenthesis.

4a³ + 7a²b + 6b³ + a³ + 2a²b + 4b²

Add like terms.

(4a³ + a³) + (7a²b + 2a²b) + (6b² + 4b²)

Simplify.

5a³ + 9a²b + 10b²

~Hope I helped!~

Saturn is 8.867 × 108 miles away from the Sun. Uranus is 1.787 × 109 miles away from the Sun. Approximately how many times farth
GrogVix [38]

Answer:

0.2 times

Step-by-step explanation:

Saturn: 8.867 × 108 = 957.636

Uranus: 1.787 × 109 = 194.783

You take (Uranus: 194.783)

& you divide it by (Saturn: 957.636)

You should get a funky number like 0.203399830415732 but since they said approximately you only need to use the first 2 (don't forget to round)

That would make Uranus 0.2 times as far from the sun

What percent of 146 is 39​
marissa [1.9K]

Answer:

<em>39 is 26.71% of 146</em>

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 146 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 146.

Step 4: In the same vein, x% = 39.

Step 5: This gives us a pair of simple equations:

100% = 146(1).

x%=39(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

100/x% = 146/39

Step 7: Taking the inverse (or reciprocal) of both sides yields

x% / 100% = 39/146    ⇒ x= 26.71%

Therefore, 39 is 26.71% of 146.

<em>hope it helps:)</em>

You roll 2 number cubes. What is the probability of rolling double twos?<br> EZ points!
Misha Larkins [42]

Answer:

Step-by-step explanation:

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
