Mathematics
1 answer:
meriva2 years ago
6 0

Answer:

1) E

2) D

3) G

4) I

Step-by-step explanation:

1)

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

2)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

3)

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

4)

P = 17b + 3

P = 17(6) + 3

P = 102 + 3

P = 105

marusya05 [52]
It would be 10 because 7000 can go into 70,000 10 times. You can you a calculator or look at the zeros take away the 3 zeros in 7000 and then 3 zeros in 70,000 making it 7 and 70 and 7 goes into 70 10 times as well. I hope this helps!

5. The denominator of a fraction exceeds the numerator of a fraction by 25.
Nostrana [21]

9514 1404 393

Answer:

  15/40

Step-by-step explanation:

The difference between denominator and numerator in 3/8 is 8-3 = 5. In order to get an equal-value fraction with that difference being 25, each of the numbers must be multiplied by 5:

  3/8 = 15/40

The number is 15/40.

SOMEONE PLEASE HELP....
Anton [14]

Answer:

Step-by-step explanation:

(3x+4)(x^2+px+5) \\=3x^3+3px^2+15x+4x^2+4px+20\\=3x^3+(3p+4)x^2+(15+4p)x +20

since we know that x^2  in this expansion is -23x^{2}

thus 3p+4=-23\\3p=-27\\p=-9

Hope that helps!
