Answer:

Step-by-step explanation:

9. f(g(-n))

g(-n) = -(n²+5) = -n²-5

f(g(-n)) = 2n+1 (-n²-5 )

2n(-n²-5)+1(-n²-5 )

-2n³-10n-n²-5

-2n³-n²-10n-5

n²(-2n-1) +5(2n-1)

(n²+5)(2n-1)

10. (2x+2)(x³+3)

2x(x³+3)+2(x³+3)

2x⁴ + 2x³ +6x +6

2x³(x+1)+6(x+1)

(2x³+6)(x+1

lys-0071 [83]

Answer:

The two column proof is presented as follows;

Statement                   {}                  Reason

1. Parallelogram SUPN \overline {SR}⊥ \overline {UN} {}   1. Given

and \overline {MP}⊥ \overline {UN}

2. ∠SRU = ∠PMN = 90°   {}                 2. Definition of perpendicular lines

3. ∠SRU ≅ ∠PMN            {}                 2. Definition of congruency

4. \overline {UP} ║ \overline {SN}                      {}                4. Opposite sides of a parallelogram are                                            {}                                                               congruent

5. ∠SNR ≅ ∠PUM             {}               5. Alternate interior angles are congruent

6. \overline {UP} ≅ \overline {SN}                      {}               6. Opposite sides of a parallelogram are                                            {}                                                              congruent

7. ΔPMU ≅ ΔSRN                 {}           7. By AAS rule of congruency

By the Angle-Angle-Side (AAS) rule of congruency, we have that, if two angles and a corresponding adjacent side (∠SRU ≅ ∠PMN, ∠SNR ≅ ∠PUM, \overline {UP} ≅ \overline {SN})  of two triangles (ΔPMU and ΔSRN) are congruent, then the the two triangles are also congruent (ΔPMU ≅ ΔSRN)

Raphael paid $ 160$160 for a camera during a 75 %75% off sale. What was the​ camera's regular​ price?
Kay [80]
So paid160


75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost
