Foil (x+9)(3x-4) i have been stuck for ever

Step-by-step explanation:

The foil method is used when multiplying 2 binomials. One is (x+9) and another is (3x-4). The steps of FOIL are:

Let's do the steps on our problem:

1. multiply x and 3x. So we have x * 3x = 3x^2

2. multiply x and -4. So we have x * -4 = -4x

3. Multiply 9 and 3x. So we have 27x

4. Multiply 9 and -4. So we have -36

Listing the terms, we have:  3x^2 -4x + 27x - 36

We combine like terms and have:  3x^2 + 23x - 36

That's our answer.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
