Answer:

The answer to your question is (x + 3)

Step-by-step explanation:

$\frac{5x + 5}{x} \frac{x^{3}+ 3x^{2}}{x^{2} - 1} \frac{x - 1}{5x}$

Factor the expression

$\frac{5(x + 1)}{x} \frac{x^{2}(x + 3)}{(x - 1)(x + 1)} \frac{x - 1}{5x}$

Simplify

Cancel 5 because is in both numerator and denominator

Cancel (x + 1) because is in both numerator and denominator

Cancel (x - 1) because is in both numerator and denominator

Cancel x² because is in both numerator and denominator

After simplifying, the result is (x + 3)

Answer:

D 180 in²

Step-by-step explanation:

step 1

2 (l) (w) + 2 (l) (h) + 2(h) (w)

step 2

2×(6)×(3) + 2×(6)×(8) + 2×(8)×(3)

step 3

2×(18) + 2×(48) + 2×(24)

step4

36 + 96 + 48 = 180 in²

Which ordered pair is a solution of the equation y = 3x - 3?

iris [78.8K]

(2,3) if you plug in the Y you get 3 on the left side and then you plug in 2 and get 3*2 - 3 which is 6-3 when is 3 as well . So both values on either side are equivalent

What are the missing parts that correctly complete the proof

bonufazy [111]

Answer:

2. $\overline{AX}\cong \overline{BX}$

3. $PX \perp AB$ - definition of perpendicular

4. $\angle PXA \cong \angle PXB$ - all right angles are congruent

6. $\triangle AXP\cong \triangle BXP$

7. $\overline{PA} \cong \overline{PB}$

Step-by-step explanation:

Given: Point P is the perpendicular bisector of AB

Prove: P is equidistant from the endpoints AB

Proof.

1. Point P is on the perpendicular bisector of AB - given

2. $\overline{AX}\cong \overline{BX}$ - definition of bisector

3. $PX \perp AB$ - definition of perpendicular

4. $\angle PXA \cong \angle PXB$ - all right angles are congruent

5. $\overline{PX} \cong \overline{PX}$ - reflexive property of congruence

6. $\triangle AXP\cong \triangle BXP$ - SAS congruency postulate

7. $\overline{PA} \cong \overline{PB}$ - corresponding parts of congruent triangles are congruent

8. Point P is equidistant from the endpoints of AB - definition of equidistant
