Answer:

-2x + 12

Step-by-step explanation:

If we call our other expression y, we can set up an equation tying together 3x + 5, y, and 5x - 7:

(5x-7)+y=3x+5

Solving for y by subtracting 5x - 7 from both sides will get us the expression we're looking for:

y=3x+5-(5x-7)\\y=3x+5-5x+7\\y=-2x+12

So the other expression in the sum is -2x + 12.

Which of the following are prime factorizations of the number 70? Check all<br> that apply.
Shtirlitz [24]

The prime factorization of 70 is 2*5*7

Further explanation:

First of all let us define prime factorization

Prime factorization consists of all the prime multiples of a number i.e. the factors should also be prime numbers

Given number is 70

The multiples of 70 are

70 = 2*35 => 35 is composite number

70 = 5*14 => 14 is a composite number

70 = 7*10 => 10 is a composite number

70 = 2*5*7 => All factors are prime so

The prime factorization of 70 is 2*5*7
