polet [3.4K]

Answer:

9(p + q)(9p + 9q - 1)

Step-by-step explanation:

Given

81(p + q)² - 9p - 9q ← factor out - 9 from these 2 terms

= 81(p + q)² - 9(p + q) ← factor out 9(p + q) from each term

= 9(p + q)(9(p + q) - 1)

= 9(p + q)(9p + 9q - 1)

Find the difference in simplest form. 2b/b^2-2b+1 - 2/b^2-2b+1

kolezko [41]

1) factor the denominators: 2b/(b-1)2 - 2/ (b-1)2
2) MAKE SURE YOU HAVE A COMMON DENOMINATOR
3) combine the numerators: 2b-2/(b-1)2
4) distribute 2 from numerator: 2(b-1)/(b-1)2
5) simplify; answer is 2/(b-1)

In the diagram below, DE and EF are tangent to O. Which equation could be solved to find X, the measure of DF.

Brut [27]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Formula

m∠E = $\frac{1}{2} ( DGF - DF)$

Data

m∠E = 48°

DGF = 228°

DF = x°

Substitution

48° = $\frac{1}{2} ( 228° - x°)$

Solution

2(48) = 228 - x°

96 = 228 - x°

96 - 228 = - x°

- 132 = - x°

x° = 132°
