Factor completely. Remember to look first for a common factor. If a polynomial is prime, state this.
Yakvenalex [24]
This one is prime.  The sum of two squares doesn't factor.

The more interesting case is q^2-1, which factors into (q-1)(q+1).

Gabrielle's age is three times Mikhail's age. The sum of their ages is 56, what is Mikhail’s age?
4vir4ik [10]

the sum is 56 so 3x+x=56

3x+x=56
4x=56
x=14

John and Emily are brother and sister. John has as many brothers as sisters, and Emily has twice as many brothers as sisters. Ho
spin [16.1K]

Answer:

4 boys, 3 girls

Step-by-step explanation:

brothers of John ⇒ x

sisters of John ⇒ y

John has as many brothers as sisters:

  1. x = y

brothers of Emily ⇒ x + 1 (Emily have the same amount of brother as John, plus one (John))

sisters of Emily ⇒ y -1 (Emily have the same amount of sister as John, minus one (herself))

Emily has twice as many brothers as sisters:

  1. 2 (y-1) = x+ 1

Now we have a system of 2 equations and 2 variables

x=y (I)

2y - 2 = x + 1 (II)

____________

Replace x in equation II

2y - 2 = y + 1

2y - y = 2 + 1

y = 3

____________

Replace y in equation I

x = y = 3

That mean that John have 3 brothers plus himself, there is 4 boys in the family and John have 3 sister, so there is 3 girls in the family
