Porfavor ayudenme doy coronita

Step-by-step explanation:

Hola! Yo te puedo ayudar, pero no se como explicarlo en español muy bien, perdon en avance!

1) 5×10^3+6×10^2

  (5×1000)+(6×100)

   5000+600= 5,600

2a) 3×10^3×1.5×10^8

     (3×1000)×(1.5×10000000)

      3000×150000000= 450,000,000,000

2b) 4.2×10^3×2×10^-7

     (4.2×1000)×(2×0.0000001)

      4200×0.0000002= 0.00084

3a)

    = 2,000

3b)

      = 0.0000000000000016 o 1.6×10-10

4a) (2×10^5)^3

      200000^3= 8,000,000,000,000,000 o 8e+15

4b) (3×10^-12)^2

0.000000000003^2= 0.000000000000000000000006 o 9e-24

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
