MATH HELP PLEASE!!!! WILL MARK BRAINLIEST
Ierofanga [76]

Answer:

Prime:  x^2 + 17x - 30.

Difference of 2 squares:  256x^4 - 49x^2.

GCF:  4x^2 - 24x + 144.

Perfect Square trinomial:  4a^6 - 28a^3 + 49

Factoring Trinomial: b^2 + 5b - 36.

Step-by-step explanation:

1.  x^2 + 17x - 30 will not factor.

2.  256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)

3.   4x^2 - 24x + 144 = 4(x^2 - 6x + 36).

4.   4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.

5.    b^2 + 5b - 36 = (b + 9)(b - 4).

Mekhanik [1.2K]

                                old      new
1:   1
2:   1 x 3 = 3 ⇒        1         3       *only new members recruit 3 more
3:   3 x 3 = 9 ⇒        4         9 
4:   9 x 3 = 27⇒     13       27
5: 27 x 3 = 81 ⇒    40       81

40 + 81 = 121. Total number of members under 1 founding member.

121 x 2 founding members = 242 total number of members within 5 weeks.
