30b^4 - 45b^3 - 10b^2 + 15b \\ \\ GCF = 5b \\ \\ 5b (  \frac{30b^4}{5b} +  \frac{-45b^3}{5b} +  \frac{-10b^2}{5b} +  \frac{15b}{5b}) \\ \\ 5b(6b^3 - 9b^2 - 2b + 3) \\ \\ 5b(3b^2(2b-3)-(2b-3)) \\ \\ 5b(2b - 3)(3b^2 - 1) \\ \\

The final result is: 5b(2b - 3)(2b<span>² - 1).</span>

Solve the percent change . state if increase or decrease.
Dmitry [639]

Answer:

1.) 18 is decreasing by 83%

2.) 16 is decreasing by 12.5%

Step-by-step explanation:

Part ÷ Whole = Percent (decimal form)

1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.

2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.

Hope this helps,

On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles
german
On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles per hour from his rate on his return trip. Alfonso found that in the same amount of time he could cycle 57 miles with the wind, he could go only 33 miles against the wind.What is his normal bicycling speed with no wind?

If ΔGET≅ΔMAP, then what corresponding parts are congruent? segment TG and segment AM ∠T and ∠P segment MP and segment ET ∠E and
otez555 [7]

Answer:

2nd Option is correct that is ∠T and ∠P.

Step-by-step explanation:

We are given that ΔGET ≅ ΔMAP

We need to find Congruent part from the given options.

Since, we are given the figure of the congruent triangles with marking not any instruction with which vertex is congruent to which vertex.

So, The Given Name of the Congruent triangle.

We deduce that

G ↔ M

E ↔ A

T ↔ P

Using this we get following congruent parts,

GE ≅ MA , GT ≅ MP and ET ≅ AP

∠G ≅ ∠M ,  ∠E ≅ ∠A and ∠T ≅ ∠P.

Therefore, 2nd Option is correct that is ∠T and ∠P.
